Revision history [back]

i wrote the below code to make features detections of two images, they are shown below. the problem is despite i ahve two different images, the output Mat object of the descriptorExtractor is full of matched features with lines so much that i cant see the image..and as they are twoo different images i expected to see some few matched features..

please have alook at my code belwo and letm ke know what i am doing wrong or what i am missing.
