The quality of a digital image, often referred to as image resolution, is determined by the number of pixels and the range of brightness values available for each pixel utilized in the image. Resolution refers to the capability of the digital image to reproduce fine details that were present in the test surface. In general, the term spatial resolution is reserved to describe the number of pixels utilized in constructing and rendering a digital image. Thus, as the number of pixels acquired during sampling and quantization of a digital image increases, the spatial resolution of the image also increases. In the present LCT based investigation, the image is acquired for a window size of 461 × 345 mm². The image is digitized for 768 × 574 pixels, and provides an optical resolution of 0.6 mm/pixel. The color information available at each pixel is in the form of the R, G and B values, each over a scale of 0-255.
