To test on images of other resolutions, you have to modify the hard-coded image resolution variables in './model.py' (line:7~8). Btw, the image width and height have to be multiple of...
Yes, the in_img and gt_img is the same. So, only one of them is needed.
Yes, I met the same problem. In my opinion, it is because the CartoonGAN is only feasible to those photos that have a very similar appearance to cartoon style themselves....
你好,如果你下载的ckpt是损坏的,那可能是因为你的网速太慢导致,可以考虑在更高网速环境重新下载试试。
Any image sequence with overlap, ordered or unordered, could be stitched by our approach. For example, you can take some photos of flat floor using a smart phone. Alternatively, you...
你好!严格说我们的模型训练没有ground-truth halftone,因为在我们工作之前不存在invertible halftone的生成方法。实际上,我们训练中用到的halftone images (error-diffusion) 只是在warm-up阶段用来稳定模型训练用的, 而这些halftone images是通过传统的halftoning算法[1]从灰度图计算得到的。 [1] Victor Ostromoukhov. A simple and efficient error-diffusion algorithm. In ACM SIGGRAPH, 2001
> 您好,请问完整的训练完当时是用了多久呢,当时是在多个GPU上跑的吗? 当时用了两块12G的GPU,多线程并行训练联合优化(stage 2)大概用了两三天。
> 您好,再打扰一下,代码中的 special data 是训练的时候必须需要的吗,看您的代码中是用到了它来计算损失,它是通过某种算法获得的吗? 是训练必须的,主要用来提升halftone pattern的blue-noise property。具体信息在论文中有详细介绍。
请参考论文补充材料sec.1: http://www.cse.cuhk.edu.hk/~ttwong/papers/invhalftone/invhalftone_supp.pdf
As mentioned in the paper, higher PSNR and SSIM indicate better halftone quality because it means the more accurate simulation to the input luminance. PSNR is more focus on average...
