High Points Recognition Method of Scraped Surface Based on Background Subtraction
Using computer vision library OpenCV, a method of automatic recognition high points of scraped workpiece surface is presented. The image is dealt with by background subtraction, Median filtering, morphological processing, image negates, contour finding and drawing contours. In order to accurately and efficiently recognize the high-point contours and mark its center positions, mathematical morphology and specific processing function were used.
DESIGN OF A SEPARATING ALGORITHM FOR OVERLAPPING CELL IMAGES
The overlapping phenomenon (also called clustering) often appears in actual cell images, i.e., there are some cells clustering together to form a big area. This phenomenon causes difficulty for consequent process, so it's necessary to design an effective algorithm to separate the clustering cells into single cells. In this paper a feasible method for binary images is proposed based on mathematical morphology. First, an erosion operator is applied to determine the number of single cells from clustering cells, and then based on the erosion result, the separating points on the original binary image are searched and these separating points are used to separate the clustering cells into single cells. The design and implementation of algorithm are detailed in this paper, and the experimental results are given also.
