1.random_distortion(probability, grid_height, grid_width, magnitude) 最终选择参数为 p.random_distortion(probability=0.8, grid_height=3, grid_width=3, magnitude=6) 其他参数效果: magnitude和grid_width,grid_height越大,扭曲程度越大
· 如何实现数据增强(Data Augmentation)? 语音识别,需要大量的数据样本,试验中收集的样本个数有限,可以采用数据增强的方式扩增数据,而不改变数据中原有的信息。 音频数据常见的数据增强方式有:加噪,Shifting,Stretching Add Noise Wave Plot Shifting and Stretching Wave Plot 加噪的Python 代码如下: #coding=gbkimpor...
http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv 本书只讲Python下OpenCV基本使用,Python中导入OpenCV非常简单: importcv2 就导入成功了。 6.2 Python-OpenCV基础 6.2.1 图像的表示 前面章节已经提到过了单通道的灰度图像在计算机中的表示,就是一个8位无符号整形的矩阵。在OpenCV的C++代码中,表示图像有个专门...
imgaug:作为图像增强的库,功能很多,可以对keypoint, bounding box 同步处理(一些标记好的数据,只有同时对原始图片和标记信息同步处理,才能有更多的标记数据进行训练) import numpy as np import imgaug as ia …
