An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for image processing, in digital cameras or other devices.
Imaging. Image: a visual representation in form of a function f(x,y) where f is related to the brightness (or color) at point (x,y) Most images are defined over a rectangle. Continuous in amplitude and space.
Simple examples of periodic waveforms include the following, where is time, is wavelength, is amplitude and is phase: Sine wave: The amplitude of the waveform follows a trigonometric sine function with respect to time. Square wave: This waveform is commonly used to represent digital information.
22 Φεβ 2023 · Digital image processing is the use of algorithms and mathematical models to process and analyze digital images. The goal of digital image processing is to enhance the quality of images, extract meaningful information from images, and automate image-based tasks.
27 Ιουν 2014 · Each point on the image acts like a spherical wave source, interfering constructively or destructively with every other spherical wave in the planes beyond the image. The phases change in any given plane, and are responsible for the propagation of light.
13 Μαΐ 2020 · The processing of digital images can be divided into various classes including image enhancement, image restoration, image analysis, and image compression. Imaging provides methodology to perform some kind of operations on input images.
