1. A method comprising: accessing, by an application stored in a non-transitory memory of a computing device and executable by a processor, image data representing an image captured by a video endoscopic device, wherein the image data is encoded in a first color space; converting, by the application, the accessed image data from the first color space to a second color space, wherein the second color space is different than the first color space; identifying, by the application, a location of a feature in the image by analyzing the image data in the second color space via: grouping, by the application, pixels in the image data in the second color space into a plurality of groups based on hue values of the pixels; determining, by the application, a first group of pixels from among the plurality of groups of pixels; determining by the application, a second group of pixels from among the plurality of groups of pixels; and selecting, by the application, one of the first or second group of pixels based on a relative color difference between the first and second groups of pixels; storing, by the application, segmentation data that indicates the location of the feature in the image, wherein the segmentation data indicates the selected group of pixels; and displaying, by the application, based on the segmentation data, the image with an indication of the identified location of the feature.
