Hello
I want to extract feature from a color image using SIFT descriptor.
I do not want to convert the image to grayscale and then extract SIFT features.
I want to directly SIFT features extracted from a color image. because color information is important for me.

Hello saber,
You can perhaps apply SIFT to each color channel separately and combine the features from each channel to form a comprehensive descriptor that includes color information. You can also consider using dimensionality reduction or other methods to combine features meaningfully.
