Color Indexing Using Wavelet based Salient Points
نویسندگان
چکیده
Color is an important attribute for image match ing and retrieval Most of the attention from the re search literature has been focused on color indexing techniques based on global color distributions How ever these global distributions have limited discrim inating power because they are unable to capture lo cal color information In this paper we present a wavelet based salient point extraction algorithm We show that extracting the color information in the loca tions given by these points provides signi cantly im proved retrieval results as compared to the global color

Image retrieval using wavelet-based salient points
Content-based Image Retrieval (CBIR) has become one of the most active research areas in the past few years. Most of the attention from the research has been focused on indexing techniques based on global feature distributions. However, these global distributions have limited discriminating power because they are unable to capture local image information. The use of interest points in content-b...
متن کاملIntergrating Salient Regions with New Perceptual Texture Features Based on Wavelet Transform for Image Retrieval
In content-based image retrieval, the representation of local properties in an image is one of the most active research issues. This paper introduces a salient region detector based on wavelet transform. The detector can extract the visually meaningful regions on an image and reflect local characteristics. An annular segmentation algorithm based on the distribution of salient regions is designe...

متن کاملDetecting Faces in Color Images Using an Adaptive Color Model and Salient Features
Face detection has many interesting applications such as a face recognition system, a surveillance system, and videolimage indexing system. In this paper, we propose a new method of face detection using an adaptive skin color model and salient features. First, we detect skin color segments by adjusting threshold window in HueSaturation(HS) subspace based on the distribution of color histogram. ...
متن کاملWavelet-Based Salient Points: Applications to Image Retrieval Using Color and Texture Features
In image retrieval, global features related to color or texture are commonly used to describe the image. The use of interest points in contentbased image retrieval allows image index to represent local properties of images. Classic corner detectors can be used for this purpose. However, they have drawbacks when applied to various natural images for image retrieval, because visual features need ...
