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和检测,具有更丰富的语义信息。 通常卷积神经网络中...
右边的边缘的图可以认为是low-level feature ， 因为只是一些表面，表观的信息，比如纹理、边缘有兴趣的...

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...
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 ...
The proposed method, termed low-level feature channel guidance net LFCGN, has two advantages: 1) it introduces a low-level feature channel attention module designed to make the model parameters more efficient and can even lead to high-level feature map generation. 2) a dynamic upsampling is ...
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...
