放大后的图片有色块

P1是原图，P2是使用realesrgan-ncnn-vulkan-20211212-windows放大后，人物的脸上出现了奇怪的色块

Have you tried set -tile size to something bigger than you image. That way you should not have tile issue.

Thanks, I tried "-t 128" and it did better but there is still tile

请问你的这个问题解决了吗。是否有可能是因为在彩色图像上应用sinc滤波器使得不同通道的幅值叠加过高了呢？
