Introduction to CMOS Image Sensors
CMOS image sensors are designed with the ability to integrate a number of processing and control functions, which lie beyond the primary task of photon collection, directly onto the sensor integrated circuit.

Basic Concepts in Digital Image Processing
Digital image processing enables virtually noise-free modification of an image in the form of a matrix of integers instead of the classical darkroom manipulations necessary for analog images and video signals.

Contrast in Optical Microscopy
When imaging specimens in the optical microscope, differences in intensity and/or color create image contrast, which allows individual features and details of the specimen to become visible. Contrast is defined as the difference in light intensity between the image and the adjacent background relative to the overall background intensity. In general, a minimum contrast value of 0.02 (2 percent) is needed by the human eye to distinguish differences between the image and its background.
