Mixup torch

Web19 sep. 2024 · So I have this code here for implementing mix-up augmentation. It's incredibly slow and I'm not sure how to make it faster. It seems like there are some operations that are unavoidable and just by nature slow like scaling images by the weight which is 0.5 then summing up each cell seems like a very slow and unavoidable operation. Web8 apr. 2024 · 1. 像素级:HSV增强、旋转、平移、缩放、剪切、透视、翻转等 2.图片级:MixUp、Cutout、CutMix、Mosaic、Copy-Paste等 3.基本图片处理方法:将图像的最长边缩放到640,短边填充到640等方法。可供使用者完成开发,调试,进行图片处理等操作。
