31Segmentation (image processing) — In computer vision, segmentation refers to the process of partitioning a digital image into multiple regions (sets of pixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more… …
32HSL and HSV — Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut away 3D models of each. Below: two dimensional plots showing two of a model’s three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case… …
33Sobel operator — The Sobel operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. At each point in… …
34Difference of Gaussians — In computer vision, Difference of Gaussians is a grayscale image enhancement algorithm that involves the subtraction of one blurred version of an original grayscale image from another, less blurred version of the original. The blurred images are… …
35Roberts Cross — In computer vision, the Roberts Cross operator is one of the earliest edge detection algorithms, which works by computing the sum of the squares of the differences between diagonally adjacent pixels. This can be accomplished by convolving the… …
36Deinterlacing — is the process of converting interlaced video, such as common analog television signals or 1080i format HDTV signals, into a non interlaced form. Interlaced video frame consists of two sub fields taken in sequence, each sequentially scanned at… …
37Marr-Hildreth algorithm — In computer vision, the Marr Hildreth algorithm is a method of detecting edges in digital images, that is continuous curves where there are strong and rapid variations in image brightness. The Marr Hildreth edge detection method is simple and… …
38Maximally stable extremal regions — Feature detection Output of a typical corner detection algorithm …
39X-ray computed tomography — For non medical computed tomography, see Industrial CT Scanning. catSCAN redirects here. For the Transformers character, see Transformers: Universe. X ray computed tomography Intervention A patient is receiving a CT scan for cancer. Outsid …
40Marr–Hildreth algorithm — In computer vision, the Marr–Hildreth algorithm is a method of detecting edges in digital images, that is continuous curves where there are strong and rapid variations in image brightness. The Marr–Hildreth edge detection method is simple and… …
