Given an image with food items, how to find out food item ROI?. It would be a great help if anybody can share any references or source code on the same.
Usually, the image is processed with a of low-pass and high pass filters combination. Then a segmentation technique is used.
For example, a useful sequence might be:
Gaussian filter + gradient magnitude filter + similarity filter + region growing technique. If you are interested I can send you sample code in C ++ for this type of application
Hi All, Thank you for all your suggestions.. I am experimenting different approaches, will post you my feedback based on results, accuracy is more important in my app.
Hi All, computing boundary of single colour item would be easy... where as if the food item has mix of multiple colours, then there is a difficulty of finding out boundary of it.. anybody could share a good material or references which helps in this scenario?
