Image Rectification and Disparity Map

Hi,

I want to ask about image rectification and disparity map, i found the demos were devided into 2 parts. How to connect the output from image rectification demo to disparity map demo ? since we need both to acquire depth map.

Thanks

Hi Hendra, I think the following link will make you understand how to rectify the stereo pair and also how to calculate their disparities.

without using computervision toolbox how can i rectify images and how can i extract the features..?

You could use just harris corners to detect feature points. This is in the corner function. Once you detect corner points in both images, you'll have to code up the rest on your own if you don't have the Computer Vision System Toolbox.
