Color Vision01:24

Color Vision

2.0K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Classification of Leukocytes

8.8K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

    Area of Science:

    • Computer Vision
    • Image Processing
    • Pattern Recognition

    Background:

    • Accurate color texture classification is crucial for many applications.
    • Traditional texture descriptors often struggle with variations in illumination.
    • Existing methods lack robustness against changes in lighting conditions.

    Purpose of the Study:

    • To develop a novel texture descriptor for color texture classification.
    • To enhance robustness against illumination variations.
    • To achieve invariance to rotation, translation, and color space transformations.

    Main Methods:

    • A novel descriptor combining Local Binary Patterns (LBPs) histogram with a new feature for local color contrast distribution.
    • The descriptor is designed to be invariant to image plane rotations and translations.
    • Evaluation performed on the Outex test suite under varying illuminants.

    Main Results:

    • The proposed descriptor significantly outperforms the original LBP and its color variants.
    • It shows superior performance even when compared to color-normalized LBP approaches.
    • The descriptor demonstrates better classification accuracy than other state-of-the-art color texture descriptors.

    Conclusions:

    • The novel texture descriptor offers superior robustness to illumination changes.
    • It provides high classification accuracy for color textures.
    • This method advances the field of illumination-invariant texture analysis.
