Replacing Image with that of a bigger size (OpenCV)

Question

I'm doing image stitching on a video and this is basically how my loop works: frame1 + frame2 = stitched replace frame1 as stitched and repeat loop.

I tried resizing frame1 to the size of stitched and then using stitched.copyTo(frame1) but that doesn't seem to work. :(

Do you guys have any suggestions?

Thanks in advance!

Answer 1

// Free data allocated for frame1
frame1.release();

// Clone stiched image
frame1 = stiched.clone();

Answer 2

I have not been working with OpenCV in a long time, but here's my sugesstion

Assuming you stitched the two images sucessfully, the MAT stiched should be the resulting image. So, instead of copying stitched to frame1, stitched.copyTo(frame1) , why not just imshow(stitched) ?

Give us what you have done so far, so we can understand your question better :D
