PSNR of the test set #39

Open wuxiaolang opened 10 months ago

wuxiaolang commented 10 months ago

Hi! I would like to inquire about how to compute the PSNR of the test set, is there a script for it? The PSNR output during the training process seems to be just for one image (see Line-423)? Why is downsampling (see Line-98) performed on images when evaluating PSNR? Are the data reported in the paper also the assessment results of downsampled images?

Hi, the PSNR is computed on new novel-view images. I use the nvs() to synthesize new images and then compute the PSNR on it. The NVS PSNR is evaluated on these images: https://connecthkuhk-my.sharepoint.com/:u:/g/personal/yuanly_connect_hku_hk/Ec1RO-NIV_BJjLpPZyb-Um8B8xae8kB0iVRj4aZCm4uj9A

Thanks for sharing the data. May I ask if it is possible to share the script for nvs?
