I have an Image , and I want to extract data of Mouth in the face from the Image only in JavaCV. Then I want to compare the same from large database of images (different emotions) and then would like to find the best matched.

I have two questions here- have two questions here- 1. 2.

How to map this with DB images as DB images are some other images , and data extracted from

emotion will be different faces. SO wont the mapping hurt or what all the steps I need to care for achieve..

"I want to extract data of emotion in the face" - i think, you're slightly wrong here. there's no such thing as "emotion data" per se.

what you can do is: train ml on your data(say, the whole face image, or landmarks acquired from it) for a classification task, and later make a prediction on similar data from test images.

maybe this helps
