Localized Rgb Color Histogram Feature Descriptor for Image Retrieval
This paper proposes a new feature descriptor, localized color descriptor for content based image retrieval (CBIR). The proposed method collects the local histograms from red (R), green (G) and blue (B) color spaces. These local histograms are collected by dividing the images into subblocks (regions). The performance of the proposed method is tested by conducting experiments on Corel-1000, natur...
متن کاملColor and Shape Index for Region-Based Image Retrieval
Most CBIR systems use low-level visual features for representation and retrieval of images. Generally such methods suffer from the problems of high-dimensionality leading to more computational time and inefficient indexing and retrieval performance. This paper focuses on a low-dimensional color and shape based indexing technique for achieving efficient and effective retrieval performance. We pr...
متن کاملImage Retrieval Using Block Color Characteristics and Spatial Pattern Correlation
We propose a new content-based image retrieval using a block color co-occurrence matrix (BCCM) and pattern correlogram. In the proposed method, the color feature vectors are extracted by using BCCM that represents the probability of the co-occurrence of two mean colors within blocks. Also the pattern feature vectors are extracted by using pattern correlogram which is combined with spatial corre...
متن کاملOne Image Reduction Algorithm for RGB Color Images
We investigate the problem of combining or aggregating several color values given in coding scheme RGB. For this reason, we study the problem of averaging values on lattices, and in particular on discrete product lattices. We study the arithemtic mean and the median on product lattices. We apply these aggregation functions in image reduction and we present a new algorithm based on the minimizat...
متن کاملWhite-point independent RGB Primaries for Color Image Encoding
We present a method to calculate sets of RGB primaries that are white-point independent and have suitable gamut properties when evaluated with regards to surface colors. These primaries can be used as a basis for defining an output-referred color encoding intended for print applications. The resulting RGB sensors are sharp, i.e. decorrelated, emphasizing again that for imaging applications, the...
