image sparse representation

基本解释

Image sparse representation data got by sparse decomposition method are compressed by quantization and coding.
在图像稀疏分解的基础上，对分解出的数据进行压缩。
Considering the good performance of sparse representation for image classification, a novel sparse representation based text detection method is presented.
针对稀疏表示具有良好的分类特性，本文提出了一种基于稀疏表示的文字检测方法。
The 2DPCA is used to obtain the feature vectors and the compressive sensing is used to get the sparse representation of the test image given enough training images.
阐述2DPCA提取特征向量的工作原理，利用压缩感知方法求解待识别图像在足够样本下的稀疏表示。
