Greetings to All,

I am working on camera captured document image analysis. i have studied some paper on features extraction from combination of two or more texture features. Now i wish to know what is the significance of the combining the many features to extract from document image. i have seen some papers where they have used features like (LBP+HoG), (LBP+LPQ+GLCM+HOG) and so on.

Please clarify things.

Thanks..
