Thanks | The two numbers are measuring different things.

Do you mean after calling impoly, you go into the figure window and select "Generate Code"? Which will create a function 'createfigure' - but this has nothing to do with 'impoly'.
There are a couple of ways you can extract the ROI.
After choosing the area with 'impoly', before closing the figure:
'BW = createMask(h);'
Or you can extract the position with 'getPosition' and then use 'roipoly'. | |

<IMAGE> | Because if you construct a foreign key, Django will construct a "twin field" that stores the primary key of the object. The foreign key itself is thus more a "proxy" field that fetches the object.

<IMAGE>
Can anyone help me out here by explaining the reason of these grey values.
Thank You | I assume you use the mean of the three components instead of the function 'rgb2gray' because it has some advantages in your case. ('rgb2gray' does something similar: it uses a weighted sum).
Subtracting the minimum and dividing by the maximum doesn't convert your image to binary. It will only scale all values to the range (0,1), which is the case in your example. This only means that all values are 0 and 1, not exactly 0 or 1. If you want a binary image, i.e. only 0 and 1, you will need to use a threshold to convert the grayscale image to binary.
A method which is often used, is to calculate a threshold using Otsu's method:
'''
threshold = graythresh(im); % calculate threshold
binaryImage = im2bw(im,threshold); % convert image to binary
'''
If your image is saved as 'uint8' then normalizing the image should convert your image to binary, as 'uint8' only can handle integer numbers and any numbers between are rounded. That means you assume the optimal threshold to be at 0.5. | |

9,723,281 | 1 | 9,726,114 | After spending yesterday afternoon looking through SO and online, and not quite finding what I think I need, I wanted to ask the community for suggestions. I have a specific interaction I'm trying to prototype and am guessing there is a plugin I can use instead of start from scratch, but can't quite find it.
The interaction is a long horizontal reveal and slide. The app opens with one div visible. The user swipes or clicks to the right, and the first div slides left (but not entirely off screen) and the second div both fades in and moves into the space where the first div was. Interaction continues for as many panes as there are (for this prototype we have five levels deep). user can back in and out at will--I planned to show this by clicking the left and right sides of the visible div, as the design shows a big grey bar with an arrow fading in on each side. Moving back 'up' is reverse of going 'down'--divs fade off and the previous div slides into place.
Touch is required for this demo/prototype.
As requested, here is a sketch:
<IMAGE> | Thought I would take a stab at a prototype. The dimensions are tiny because it's in jsfiddle, but you can expand the results window and change the dimensions if you wish. I only tested this in Chrome and it uses a lot of CSS3:

> Suppose we are maintaining a data structure under a series of n operations.
Let f(k) denote the actual running time of the kth
operation. For each of the following functions f, determine the
resulting amortized cost of a single operation. (For practice, try all
of the methods described in this note.)(a) f(k) is the largest integer i such that 2^i divides k.

'''
k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ...
f(k) 0 1 1 2 2 2 2 3 3 3 3 3 3 3 3 4 ...
'''
I don't see where the potential method could help here as the operations just get more expensive over time. Banker's Method also doesn't seem to be applicable here for the same reason. So I thought aggregate method would be most suitable.
<IMAGE>
is what I came up with for a sequence of n operations, however I can't seem to transform it, which makes me question whether or not it's the right approach.
EDIT: so it looks like I misunderstood the question I think the correct table would look like this:
'''
k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ...
f(k) 0 1 0 2 0 1 0 3 0 1 0 1 0 1 0 4 ...
''' | quick answer in case anybody googles this
using the banker's method you can 'save' a constant amount of credits (in this case 2 per operation would work) and easily cover the costs of the more expensive ones down the line.
'''
k 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ...

24,217,020 | 1 | 24,217,215 | Well, I have been doing some experiment with QT lately, I have a touchscreen Linux PC and I connect it to the WiFi network. Instead of pinging a network old fashioned way I thought of making an app for it.
The interface is like, I would enter an IP address and the application will ping the network and let me know if the IP is ping-able or not. When the IP is getting pinged Green Check will be shown, if not getting pinged then Red Check will be shown.
My progress is, I am able to take the IP in a script file and ping it. But the problem is how to interface the ping reply with the application. i.e. the two labels (Green and Red Check) ???
Thanks in advance. My GUI looks like this.
<IMAGE> | There isn't a good cross platform way for doing this. But you can use platform specific ways :
On Linux you can :
'''

if (returnedCode == 0)
{
// It's active, Show Green Check

'''

So what was happening is, the text would end up being a few pixels longer in different browsers, throwing off the ending of how long the input box was.
It has come to my attention that different browsers inevitably will render some font's slightly differently and there really is no work around for letter-spacing.
So, instead of changing the letter spacing so that the input box's matched - I made the input boxes fill the remaining space of the div that it was inside with a percent rather than a pixel length. This way, each input box ended at the same point in all the browsers and ended up matching.
Thanks for your help everyone.

I have the 'Android' code for storing pictures in database. How can I compare a stored picture with a picture that is taken? | There could be several right answers, depending on what you're looking for.
If you're talking about comparing a new photo made with the on-device camera, there's virtually no chance it will be a byte-for-byte match with any existing file.
If you want to detect an exact match from a source where a copy is likely, look at the file size and dimensions of the two images. If they are exactly the same, then you can look at the bytes. To save time, store a digital signature (e.g., an MD5 or SHA1) hash of the contents in the database along with the image.
If you want to find whether the images are similar in appearance, then you'll have to find some way to characterize the image. I'm no expert at this, but in my naive approach, I'd do something like divide the image into a fixed number of regions and measure the amount of red, green and blue in each region. You could even do this recursively on ever-smaller regions as approximate matches are found. Comparing whole images will be a lot easier than finding a partial match. | |

ndslr | The way you're exporting your jar, your library jar isn't automatically added to the output jar. You would have to specify the classpath when you run it:
'''
java -cp "C:\Users\Andy\Desktop\mysql-connector.jar;YourOutputJar.jar" TS3BotMySQL

Instead, you have to add the mysql-connector.jar to your output jar. To do this, instead of going to export > jar, go to export > jar, and then select "Extract required libraries into generated JAR" or "Package required libraries into generated JAR" at the prompt.

18,841,792 | 1 | 18,863,454 | This is turing into a bit of a brain buster, but I assume there is a very simple and efficient method to do this.
In my app I have views laid out in a grid. Views can be moved to any location via gesture. The problem is making the view sort to just the right location after the gesture event. Basically I am doing this. Works sort of but not correct yet.
: the tag of the views will always update to the current position of the view in the grid.
Below is the code I am using to sort, and here is <URL>.
'''
-(void)sortViews:(UIView*)myView {
__block int newIndex;
// myView is the view that was moved.
[viewsArray removeObject:myView];
[viewsArray enumerateObjectsUsingBlock:^(UIView *view, NSUInteger idx, BOOL *stop){
if (myView.center.x > view.center.x) {
if (myView.center.y > view.center.y) {
newIndex = view.tag -1;
*stop = YES;
} else {
newIndex = view.tag +1;
*stop = YES;
}
} else if (myView.center.x < view.center.x) {
if (myView.center.y > view.center.y) {
newIndex = view.tag -1;
*stop = YES;
} else {
newIndex = view.tag +1;
*stop = YES;
}
}
}];
if (newIndex < 0) {
newIndex = 0;
} else if (newIndex > 5) {
newIndex = 5;
}
[viewsArray insertObject:myView atIndex:newIndex];
[UIView animateWithDuration:.4 animations:^{
[self arrangeGrid];
}];
}

18,243,014 | 1 | 18,243,153 | I am wondering specifically about the wrapper and how to structure the site. I have all content contained within 960 pixels, except for the header image (which is below the navigation). I've attached an image below.
If I'm understanding correctly, I've read in some places to place the header image outside the wrapper, others say within.
Any clarification would be greatly appreciated, I know there are so many ways to do this, but I'd like it to be really clean and adhere to recent standards. I'm using HTML5, not that it matters much.
<IMAGE> | You can create a wrapper class, and but use it only where you need it. So, in your case it would go like this...
- - - - -
That way, although it might seem chopped out, you'll get the desired behaviour, those elements in wrapper having the 'normal' width, while the other go the full width, by default.
See how that works <URL>.
This is essential (and also obligatory by SO):
'''
div {background: #eee; height: 50px;}
div.wrapper {background: #ccc; width: 200px; margin: auto;}
'''
EDIT
And since you want to keep your footer together, not in two separate parts (which makes perfect sense), you can do this, it works too:
'''
<div id="footer">
<div class="wrapper"></div>
</div>
'''
And if you don't want your wide elements to scale, you can define their width, too... Like having a bigger wrapper for those. You can also center the background and never worry about it (thanks @kennypu). Plenty of options once you tame your wrappers.
Note: I might've not used the proper terminology, as wrapper is wrapping only parts of the site and not the whole thing (maybe you can think of it as a limiter), but you get the point. | |

Second, Depending on how your views are laid out, especially if you have views next to each other, that code might not work. It'll also not work if there is vertical margin/space in between the subviews. Instead, you might try this code when looping through the subviews:
'''
for (UIView *view in scroller.subviews){
if (scrollViewHeight < view.frame.origin.y + view.frame.size.height) scrollViewHeight = view.frame.origin.y + view.frame.size.height;
