Matching sketch(Drwing) face into digital color photo

[Andrea00001]

Hey guys

im going to match the sketch face (drawing photo) in to the color photo. so for the research i want to find out what are the challenges that matching sketch drawing in to color faces.

for now i have find out that

1. resolution pixel difference 2. texture difference 3. distance difference 4. and color (not much effect)

i wanna know that in technical terms what are other challenges can comes when detecting fearures and extracting features and matching them

and what are available OPEN CV and JAVA CV method and algorithms to overcome that challenges????

please tell me the answers very soon hope some experts will help me thanx

Hey Andrea00001

LabVIEW can call OpenCV dlls, but that's about where the support for OpenCV and JavaCV ends.

But I was able to find another forum and resources that may help you in your application.

This link compares different feature descriptors.

This link compares different algorithms.

This link discussed finding objects based on a reference object

This link does a simpler search for object orientation

For future LabVIEW related issues I highly recommend posting on these forums.
