2. Gamma correction - Wikipedia

   en.wikipedia.org/wiki/Gamma_correction

   In CRT displays, the light intensity varies nonlinearly with the electron-gun voltage. Altering the input signal by gamma compression can cancel this nonlinearity, such that the output picture has the intended luminance. However, the gamma characteristics of the display device do not play a factor in the gamma encoding of images and video.

3. Wikipedia:How to improve image quality - Wikipedia

   en.wikipedia.org/wiki/Wikipedia:How_to_improve...

   Images can often be improved – or even transformed – by using graphics software such as Photoshop or the free GIMP and Paint.NET applications. Many other programs also have photo-enhancing tools, including facilities for semi-automatic image enhancement, so that you need only click a button, or choose a thumbnail, to have a positive effect on image quality.

4. Common Intermediate Format - Wikipedia

   en.wikipedia.org/wiki/Common_Intermediate_Format

   The simple way to convert NTSC video to CIF is to capture every other field (e.g., the top fields) of interlaced video, downsample it by 2:1 horizontally to convert 704 samples per line to 352 samples per line, and upsample it vertically by a ratio of 6:5 vertically to convert 240 lines to 288 lines.

5. Video post-processing - Wikipedia

   en.wikipedia.org/wiki/Video_post-processing

   Video post-processing is the process of changing the perceived quality of a video on playback (done after the decoding process). Image scaling routines such as linear interpolation, bilinear interpolation, or cubic interpolation can for example be performed when increasing the size of images; this involves either subsampling (reducing or shrinking an image) or zooming (enlarging an image).

6. Video compression picture types - Wikipedia

   en.wikipedia.org/wiki/Video_compression_picture...

   Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame. For example, in a scene where a car moves across a stationary background, only the ...

7. 2D to 3D conversion - Wikipedia

   en.wikipedia.org/wiki/2D_to_3D_conversion

   If done properly and thoroughly, the conversion produces stereo video of similar quality to "native" stereo video which is shot in stereo and accurately adjusted and aligned in post-production. [ 1 ] Two approaches to stereo conversion can be loosely defined: quality semiautomatic conversion for cinema and high quality 3DTV, and low-quality ...
