The problem has the following challenges: Highly noisy images Low texture\/contrast High inter-class similarity Limited in quantity Solution Noise reduction technique was used to smooth the images. Unet deep learning then is applied to detect objects. Finally, draw and measure the bounding box of the detected objects.
