Not surprisingly re-using a 1-object classifier model can help a lot to solve the multi-object problem. Segmentation is one of the most crucial tasks in image processing and computer vision. it works for our image data set. When possible, bots have a 'headless' mode, which allows them to execute a processing pipeline as a typical Matlab function, either on an image or a folder of images. Segmentation of an image entails the division or separation of the image into regions of similar attributes. Do I just cut-out that segment of the image and save it as its own image and feed to that to YOLO? You need as much images as you can get of your microbial organism, in different sizes, positions, etc. It was originally introduced by Xu and Prince to drive snakes, or active contours, towards edges of interest in image segmentation.
