“…We used an RGB (Red, Green, Blue) color model and an HSV (Hue, Saturation, Value) color model. The RGB color model is used for many image retrieval systems (Jain & Valilaya, 1996;Kim & Chung, 2003). For global image representation and fast search, RGB color histograms of the image, which are quantized into 16 bins per R, G, and B coordinates, are extracted.…”
