A Robust Descriptor for Color Texture Classification Under Varying Illumination
Classifying color textures under varying illumination sources remains challenging. To address this issue, this paper introduces a new descriptor for color texture classification, which is robust to changes in the scene illumination. The proposed descriptor, named Color Intensity Local Mapped Pattern (CILMP), incorporates relevant information about the color and texture patterns from the image i...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملExtended color local mapped pattern for color texture classification under varying illumination
This paper presents a color–texture descriptor based on the local mapped pattern approach for color–texture classification under different lighting conditions. The proposed descriptor, namely extended color local mapped pattern (ECLMP), considers the magnitude of the color vectors inside the RGB cube to extract color–texture information from the images. These features are combined with texture ...
متن کاملAn Illumination Invariant Image Descriptor for Color Image Matching
Color image descriptors have been used extensively and successfully in many computer vision applications. However, object colors are sensitive to illumination changes which in turns will affect the performance of object recognition if the image descriptors used are not robust to these changes. To increase photometric invariance and discriminative power, this study proposes an image descriptor f...
