如何处理不同尺寸大小的图片在CNN中训练? answer:不关心压缩图像,网络可能会学会理解内容;无论如何,缩放和透视对内容意味着什么? 将图像中心裁剪为特定大小,如果您担心丢失数据,请进行多种裁剪并使用这些裁剪来增加输入数据,以便将原始图像分成N个不同的正确大小的图像 将图像用纯色填充到平方大小,然后调整大小。 做一个这样的组合 Depending on how far you want or need to go, there actually is a paper here called Spatial Pyramid Pooling in Deep Convolution Networks for Visual Recognition that handles inputs of arbitrary sizes by processing them in a very special way. 做修改
