The result of metric is -nan
Hello, I use this code on Linux, make and run:
./360tools_metric -w 4096 -h 2048 -f 1 -o ../Video02-150Frame/video02-Re.jpg -q 1 -l 4096-m 2048 -t 1 -r ../Video02-150Frame/video02-3MB-264.jpg -n 1 -x 1
then the result is:
QM_ID=1 -nan -nan -nan
both distorted image and reference image are same width and height, same Equirectangular projection, and I don't know what's wrong.
What does the result mean
when i do 360tools_metric, and the results show "QM_ID=1 8.82 8.64 8.56". could you tell me what the three numbers behind QM_ID mean?

It is reproducible here with any file, i.e. no special crafted file needed.
how to calculate s-psnr
how to use the file(sphere_655362.txt)?
why the number of point is 655362?

It's possible a more extensive explanation of the input parameters? like num_vertical_segments affects the output transformations?

the cubemap projection
Hi,
I use the following command line to generate a cubemap projection.
./360tools_conv -i ERP.yuv -o CMP.yuv -w 3840 -h 1920 -f 3 -l 3840 -m 2880 -n 1
The layout of CMP should be like:
+--------+--------+--------+--------+ 1
| | | | |
| | 1 | | |
| | | | |
+--------+--------+--------+--------+ H/3
| | | | |
| 2 | 3 | 4 | 5 |
| | | | |
+--------+--------+--------+--------+ H/3*2
| | | | |
| | 6 | | |
| | | | |
+--------+--------+--------+--------+
1 W/4 W/2 W/4*3
For my input YUV file, the width and height of each square of CMP should be 960. Therefore, the value of output Y(1:960, 1:960) should be 0. But this square indeed has non-zero value on the edge of the square:
The same problem occurs in other square:
Why did this happened?

the implementation of pitch and yaw
Hi,
I have a question about the two parameters pitch and yaw. To my point of view, applying these two parameters should result in a rotated projection with certain pitch and yaw angle.
Therefore, when I use the command line bellow to generate a cubemap projection with a yaw angle (180 degree) and a default pitch angle (90 degree), it seems that your code does not work.
./360tools_conv -i ERP.yuv -o ERP2CMP.yuv -w 3840 -h 1920 -f 3 -l 3840 -m 2880 -n 1 -x 1 -y 1 -p 90 -t 180
Or maybe I have the wrong comprehension on these two parameters.
Thank you very much!

Lan
Viewport from 360 video frame.
Hi there,
I have seen the transformations that 360tools do and I see how powerful it is.
However I am developing a project and I would like to extract a viewport from a 360 video frame? Does this tool do this conversion?
I have studied the code and I have not found it.
Could you please help me?
Regards,
Dario
CPP-PSNR calculation ERP & ERP with different resolutions
I tred to calculate CPP-PSNR of two ERP sequences but of different size (i.e, 3840x1920 and 3328x1664). The software throws an error. I debug into it and see it fails at resampling process (using lanczos).
Why is the ERP video before projection different from the ERP video after back projection?
1.The ERP video I used is:
2.Get the TSP projection video through the following command.
Command used for TSP projection:
Video with TSP projection:
3.Back-project the obtained TSP video.
Command used for TSP back projection
Video with TSP back projection：
Why is the ERP video before projection different from the ERP video after back projection?
