这里记录在学习SSD源码过程中用到的相关内容 keras.applications.imagenet_utils.preprocess_input(): 用来将读入的原始图片张量转换成为需要Imagenet网络识别的形式,源码显示的是进行通道的转换以及减去各个通道均值,这个均值应该是ImageNet上面训练数据集上的均值. keras.preprocessing.image: 包含了对图像预处理的一些基本操作,也是最常用的操作. SciPy中的io 和misc是常用的模块,imsave可以将一个…

CSharpGL(53)漫反射辐照度 本系列将通过翻译(https://learnopengl.com)这个网站上关于PBR的内容来学习PBR(Physically Based Rendering). 本系列共4篇.由于前2篇已经有人翻译过了(https://learnopengl-cn.github.io/07%20PBR/01%20Theory/),我暂时就跳过,直接翻译第3篇. 本篇讲了什么,我也不太懂.不过我在CSharpGL中已经实现了一个PBR的demo.代码都有了,早晚会懂的. 下…

小结: 1.ASCII编码.GBK编码不是变长编码: 2.数据压缩: 示例: aabacdab → 00100110111010 → |0|0|10|0|110|111|0|10| → aabacdab 3.变长编码: 符号-位长 映射: https://en.wikipedia.org/wiki/Variable-length_code https://baike.baidu.com/item/变长编码表 变长编码表是通过一种评估来源符号出现机率的方法得到的,出现机率高的字母使用较短的编码,反…
