CNN中的low-level feature 与high-level feature low-level feature:通常是指图像中的一些小的细节信息,例如边缘(edge),角(corner), 颜色(color),像素(pixels),梯度(gradients)等,这些信息可以通过滤波器、SIFT或HOG获取; hight-level feature:是建立在low level feature之上的,可以用于图像中目标或物体形状的识别...

基于内容的图像检索底层融合分类体系In previous content-based image retrieval algorithms,the most prevalent and convenient method in representing images is to extract low-level content features such as color,texture,shape or spatial information.But using only one low-level feature independently ignores the...
Causal importance of low-level feature selectivity for generalization in image recognitionCausalityNeural networkOrientation selectivityAlthough our brain and deep neural networks (DNNs) can perform high-level sensory-perception tasks, such as image or speech recognition, the inner mechanism of these ...
The purpose of feature extraction technique in image processing is to represent the image in its compact and unique form of single values for the purpose of content-based image retrieval (CBIR) is presented in this report. The CBIR problem is motivated by the need to search the exponentially ...
Local features have become an essential tool in visual recognition. Much of the progress in computer vision over the past decade has built on simple, local representations such as SIFT or HOG. SIFT in particular shifted the paradigm in feature representation. Subsequent works have often focused on...

cv?好吧默认是说现在的CNN model的feature吧,很多时候大家说的都是直观上的,low的就是小scale的,high的就是相对大scale的,可以理解为原子级别,分子级别,化合物...这种逐渐上升尺度的意思。但这是蛮感性,因为也没多少办法,大家都是可视化之后发现hierarchical model应该是这样的,sounds reasonable, make sense。 也...
