Lowpass filtering smoothes an image so that large objects are transformed into homogeneous zones and small objects are reduced in intensity and/or merged into the larger regions. In the process, edges are reduced in intensity so that the details of an object are lost and objects in close proximity to each other are combined. Highpass filtering performs the opposite function.  3, record 2, English, - lowpass%20filtering

An adaptive filter uses a filtering window that runs over the entire image pixel-by-pixel, generating new(filtered) values of the pixels.

[A filter used] to remove random noise while preserving high frequency features (edges).  3, record 9, English, - gamma%20filter

Record number: 9, Textual support number: 1 CONT

The Gamma filter performs gamma map filtering. Gamma filtering is primarily used on radar data to remove high frequency noise(speckle) while preserving high frequency features(edges). The Gamma Map filter was first proposed by Kuan.... Lopes modified the Kuan Map filter by assuming a gamma distributed scene and setting up two thresholds. The gamma filter size ranges from 1 to 11. Different filter sizes will greatly affect the quality of processed images. If the filter is too small, the noise filtering algorithm is not effective. If the filter is too large, subtle details of the image will be lost in the filtering process. A 7x7 filter usually gives the best results.... The GAMMA filter performs spatial filtering on each individual pixel in an image using the grey level values in a square window surrounding each pixel. The dimensions of the filter must be odd, and can be from 3x3 to 11x11 pixels.  2, record 9, English, - gamma%20filter

Filtering is an operation designed to improve image readability and/or to extract certain information from them. The principle of the various filters is to modify the numerical value of each pixel as a function of the neighbouring pixel values. For example, if the value of each pixel is replaced by the average of its value and those of its eight neighbours the image is smoothed, that is to say, the finer details disappear and the image appears fuzzier. In "mobile window filtering" the programme computes for a given pixel the sum of the products of the neighbouring pixel values multiplied by coefficients given in a table of coefficients, then repeats the operation for the next pixel and so on.  3, record 13, English, - filtering

Bilinear filtering is a method of anti-aliasing texture maps. A texture-aliening artifact occurs due to sampling on a finite pixel grid. Point-sampled telexes jump from one pixel to another at random times. This aliening is very noticeable on slowly rotating or moving polygons. The texture image jumps and shears along pixel boundaries. To eliminate this problem, bilinear filtering takes a weighted average of four adjacent texture pixels to create a single telex.  1, record 14, English, - bilinear%20filtering
