3. Gaussian blur - Wikipedia

   en.wikipedia.org/wiki/Gaussian_blur

   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.

4. Bloom (shader effect) - Wikipedia

   en.wikipedia.org/wiki/Bloom_(shader_effect)

   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.

5. Miniature faking - Wikipedia

   en.wikipedia.org/wiki/Miniature_faking

   A miniature can also be simulated digitally, using an image editor to blur the top and bottom of the photograph, so that only the subject is sharp. With basic techniques, e.g., a tool such as Adobe Photoshop 's Lens Blur filter, [ 9 ] using sharpness gradients extending from the middle of the image to the top and bottom, the effect is quite ...

6. Pixelization - Wikipedia

   en.wikipedia.org/wiki/Pixelization

   Pixelization (British English, pixelisation) or mosaic processing is any technique used in editing images or video, whereby an image is blurred by displaying part or all of it at a markedly lower resolution. It is primarily used for censorship. The effect is a standard graphics filter, available in all but the most basic bitmap graphics editors.

7. Display motion blur - Wikipedia

   en.wikipedia.org/wiki/Display_motion_blur

   Blur from eye tracking fast-moving objects on sample-and-hold LCD, plasma, or microdisplay. [1] [2] Resolution resampling (blur due to resizing image to fit the native resolution of the HDTV); not a motion blur. Deinterlacing by the display, and telecine processing by studios. These processes can soften images, and/or introduce motion-speed ...
