Gabor
- 本程序提供了garbo变换与反变换的功能代码
xiaobotiqu.m
- 关于小波包变化的,特征提取的一些程序,可直接运行成功。-Wavelet packet feature extraction
wavelet_edge
- % 该算法采用的是样条小波,为了更好的检测边缘,用a tuous 算法代替了mallat算法。 % 该算法和mallat快速算法主要区别: % 1 a tuous 算法不需要抽取偶数样本,所以奇异检测定位更准确,相应的重构是不需要插零。 % 2 a tuous 算法需要对滤波器进行伸缩。
work
- 小波去噪程序,用于实现对含有噪声的信号进行去噪,还是有点用。-Wavelet de-noising procedures for the realization of the noisy signal de-noising, or a bit to use.
wodeshuiyinzhuchengxv
- 这是个人在工作中的一个小的matlab源码。包含了水印过程中一些常用的步骤,从置乱技术、水印的嵌入、水印性能测试。对于做水印初入门的人有一定的借鉴意义-This is the work of individuals in a small matlab source code. Contains the watermarking process, some common steps, from the scrambling technology, watermark embedding, wate
inversefilter
- 图像的逆滤波处理。图像滤波,即在尽量保留图像细节特征的条件下对目标像的噪声进行抑制,是图像预处理中不可缺少的操作,其处理效果的好坏将直接响到后续图像处理和分析的有效性和可靠性-Inverse image filtering. Image filtering, namely, to preserve image detail characteristics of the target under the conditions as to suppress noise, image pre-proc
