watermarkfft
- 基于fft的数字水印,分别对RBG三个通道重复嵌水印,每个通道分别对fft变换域中幅度谱以圆方式,每个圆上对称的四个点重复嵌1bit水印,然后以r为步进,选更大的圆嵌入接下去的水印信息,该方法有比较好的鲁棒性-Fft-based digital watermarking were embedded watermark repeated RBG three channels, each channel separately the fft transform domain amplitude sp
OnlinePCA
- 通过在线PCA来识别手势,并能对新增手势做一定的增量,很好的实现了增量学习。算法具有效率高,识别率好,速度快等特点,同样适合其他模式识别方面的应用。-The learning method for hand gesture recognition system based on vision is commonly off-line,which results in repeated off-line learning when new hand gestures come. Its real-
GLCM-OpenCV-master
- 由于纹理是由灰度分布在空间位置上反复出现而形成的,因而在图像空间中相隔某距离的两象素之间会存在一定的灰度关系,即图像中灰度的空间相关特性。灰度共生矩阵就是一种通过研究灰度的空间相关特性来描述纹理的常用方法。 Gray-level co-occurrence matrix from an image 图像的灰度共生矩阵(Because the texture is formed by the repeated appearance of the gray distribution in the
