To tackle the differing image sizes, you’re going to rescale the images; You can easily do this with the help of the skimage or Scikit-Image library, which is a collection of algorithms for image processing. In this case, the transform module will come in handy, as it offers you a re...

其中,白化(whitening)处理或者叫标准化(standardization)处理,是对图片数据减去均值,除以方差,保证数据零均值,方差为1,如此降低输入图像的冗余性,尽量去除输入特征间的相关性,使得网络对图片的动态范围变化不敏感。 # Image processing for training the network. Note the many random# distortions applied to the imag...

首先,你要知道一个正常的卷积操作是一个卷积核划过输入区域(下图中蓝色区域)后生成一个输出区域(下图的绿色区域)。这里,输出区域的尺寸是小于输入区域的。(当然,如果你还不知道,可以先看下斯坦福大学的CS231n 课程或者论文"A guide to convolution arithmetic for deep learning"。) ...
