More details about Inference time

Hi ,I see you believe that your algorithm can work at real time speeds ,based on your observations can you predict how much time this will take to stitch 4 ,1280x720 images into one Panorama , I plan to use RTX3070 GPU and hope to use this method for video stitching

In our experiments, it usually takes less than 30s per iteration to merge the pre-processed 9000x4000 images when using a much older GPU. If you use RTX3070 to merge 1280x720 images, I think it should take less than 1s per iteration because your image is much smaller. Then, the execution time depends on how many iterations are needed. If no more than 2 images overlap in the same area, you can merge all 4 images in one iteration (see ./Test_data_4Input for example). If three or more images overlap in the same area, you need to merge them iteratively (see ./Test_data for example); in this case, you might need up to 3 iterations to merge all 4 images. Besides, you need to consider the time of pre-processing. This time depends on what parkage/algorthim you choose.
