Color Histogram-Based Image Retrieval System

We can implement a color retrieval method based on image color histograms, developing a graphical user interface (GUI) to enhance user experience. This approach effectively leverages color information from images for retrieval, enabling users to conveniently locate desired images. The implementation involves calculating color histograms using functions like cv2.calcHist() in OpenCV or imhist() in MATLAB, which quantify color distribution across RGB/HSV color spaces. Histogram comparison algorithms such as correlation, chi-square, or intersection methods are employed to measure similarity between images. Through this method, we can design an intuitive and user-friendly interface where users can easily perform image searches and browsing operations. The GUI components may include upload buttons, histogram visualization panels, and similarity score displays. Additionally, this approach helps users better understand and master the concepts and applications of image color histograms, demonstrating practical implementation of color-based image retrieval systems with real-time processing capabilities.
