| | 365 | - a frequency filtering domain filter relying on the FFT utils in libavcodec. For example something like this: http://david.li/filtering |
| | 366 | - a filter computing image statistics: for each frame the filter should compute and expose as metadata information. For example such a filter could compute the moments (average, deviation, third and fourth moment) |
| | 367 | - a generic convolution filter (this may require a syntax for specifying a matrix, this could be the qualification task) |
| | 368 | - a filter to extract a palette of an image, or to replace the palette of an image with a custom one. The replacement should be done replacing each color with the most similar color. Preliminary work would consist into defining a format to specify a palette. |
| | 369 | - extend the showwaves filter to make it possible to set the color of each line. Ideally it should also be possible to map each channel to a different color. |
