An example of an image blurred using a box blur. A box blur (also known as a box linear filter) is a spatial domain linear filter in which each pixel in the resulting image has a value equal to the average value of its neighboring pixels in the input image. It is a form of low-pass ("blurring") filter.
In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more.This is accomplished by doing a convolution between the kernel and an image.
An example of bloom in a computer-generated image (from Elephants Dream). The light on the bright background bleeds on the darker areas, such as the walls and the characters. An example of bloom in a picture taken with a camera. Note the blue fringe that is particularly noticeable along the right edge of the window.
The term comes from the Japanese word boke (暈け/ボケ), which means "blur" or "haze", resulting in boke-aji (ボケ味), the "blur quality".This is derived as a noun form of the verb bokeru, which is written in several ways, [7] with additional meanings and nuances: 暈ける refers to being blurry, hazy or out-of-focus, whereas the 惚ける and 呆ける spellings refer to being mentally ...
The difference between a small and large Gaussian blur. In image processing, a Gaussian blur (also known as Gaussian smoothing) is the result of blurring an image by a Gaussian function (named after mathematician and scientist Carl Friedrich Gauss). It is a widely used effect in graphics software, typically to reduce image noise and reduce detail.
An example of anisotropic mipmap image storage: the principal image on the top left is accompanied by filtered, linearly transformed copies of reduced size. Isotropic mipmap of the same image. Anisotropic filtering enhances texture sharpness, counteracting the blur introduced by mipmapping, a common anti-aliasing technique.
In this updated print, the image of the large ocean wave shifts from the traditional style of the Japanese woodcut print to a pixelized image and finally to a wireframe model computer graphics image. [1] [2] Westworld (1973) was the first feature film to use digital image processing to pixelize photography to simulate an android's point of view.
The degree of image blurring for a given amount of focus shift depends inversely on the lens f-number. Low f-numbers, such as f /1.4 to f / 2.8, are very sensitive to defocus and have very shallow depths of focus. High f-numbers, in the f / 16 to f / 32 range, are highly tolerant of defocus, and consequently have large depths of focus.
