In computer vision, the bag-of-visual words(BOV) approach has been shown to yield state-of-the-art results. To improve BOV model, we use sparse codes of SIFT features instead of previous vector quantization (VQ) such as k-means, due to more quantization errors of VQ. And as local features in most categories have spatial dependence in real world, we use neighbor features of one local feature as its...
Image categorization plays an important role in the field of image retrieval and automatic annotation. Most existing algorithms adopted the low-level visual features to represent an image and the well-known Bag-of-words model followed by the SVM classifier was employed to fulfill the classification task. In this paper, instead of using the traditional low-level visual features, we employ the perception...
Texture is an important property of fire smoke, which is a significant signal for early fire detection. This paper describes a method of analyzing the texture of fire smoke combining two innovative texture analysis tools, Wavelet Analysis and Gray Level Cooccurrence Matrices (GLCM). Tree-Structured Wavelet transform is used to represent the textural images and GLCM are used to compute the different...
