hw3_release Extra Credit: Stitching Multiple Images?

[lgqfhwy]

Hello, I am a beginner. In hw3_release Extra Credit: Stitching Multiple Images, I don't know how to do. The problem said given a sequence of m images, then stitch an ordered chain of images. I want to take the first and second images then stitch together, formed a new images, then stitch together the third images. But it is too complex and maybe have some simple ways. I notice that you haven't do this problem, if you have any idea, please complete the code. I am a beginner, it is too hard for me. Thank you so much.

@lgqfhwy Hello, thanks for your issue, I'm a beginner too. The code has been uploaded, you can check it.

The basic idea is to perform as the hint says:

• First compute the transform matrix for every Image_i+1 to Image_i
• Then select a image to be the reference image (here I choose image2), compute the transform matrix for other image to the reference image, remember the transform matrix can be multiplied in chain (i.e., H12.dot(H23) transforms image3 to image1), also it can be multiplied reversely (i.e., inv(H12) transforms image1 to image2)
• Finally merge the warped images together, I am not sure how to do it perfectly as well so I just copy the former part of the code, but it looks not so bad :)
