'demo_ASIFT' is not recognized as an internal or external command, operable program or batch file.

sir when i run ASIFT code i m getting this error please help me sir.my coding are here, file_img1 = 'adam1.png'; file_img2 = 'adam2.png'; imgOutVert = 'imgOutVert.png'; imgOutHori = 'imgOutHori.png'; matchings = 'matchings.txt'; keys1 = 'keys1.txt'; keys2 = 'keys2.txt'; flag_resize = 0;

Hi Vani,

First of all, please have a look into the guideline for posting a question in the following link:

• TUTORIAL: how to ask a question (on Answers) and get a fast answer

This will help you as well as us in getting a solution fast. Also the please don't post the entire code if you know which are the potential areas of error in the code.

Another thing, please provide a summary of what exactly are you doing. this will help us to get a starting point.

Thanks

Nikhil
