Analyze

Table of Contents

Analyze objects of interest is the last step of a usual pipeline of image processing and allows to quantify or describe image features...

The various steps of image processing (enhance brightness/contrast,  filters, subtract background, etc.) and of segmentation allow to get a clean and (almost) perfect partitioned image ready to the analysis of image features.
