* | lavfi/delogo: band width must be at least 1Jean Delvare2013-07-05
| | | | | | | | | | | | | | | | | | | | We need at least one pixel around the logo to use as known points to interpolate from. So properly declare the band/t attribute has having a minimum value of 1.

* | lavfi/delogo: option show shouldn't affect bandJean Delvare2013-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Options "show" and "band" are unrelated and should thus be independent. However, setting "show" to 1 currently resets "band" to its default value of 4. While this is documented, this still surprising and confusing IMHO. Change this behavior and make "show" and "band" independent from each other. Update the documentation accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The left and right samples are the same for the whole line, so store their values and don't recompute them for every iteration of "y". This simple optimization results in a speed improvement between 15% and 20% in my tests (depending on the logo geometry.) Result is obviously the same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The top left hand corner pixel coordinates are already stored in logo_x1 and logo_y1 so don't recompute each of them 6 times for every iteration. This is a simple code optimization, result is obviously the same. The performance gain is small (about 2% in my tests) but still good to have, and the new code is clearer.

* | lavfi/delogo: avoid propagation of rounding errors in chroma planesJean Delvare2013-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating on subsampled chroma planes, some rounding is taking place. The left and top borders are rounded down while the width and height are rounded up, so all rounding is done outward to guarantee the logo area is fully covered. The problem is that the width and height are counted from the unrounded left and top borders, respectively. So if the left or top border position has indeed been rounded down, and the width or height needs no rounding (up), the position of the the right or bottom border will be effectively rounded down, i.e. inward. The issue can easily be seen with a yuv240p input and -vf delogo=45:45:60:40:show=1 -vframes 1 delogo-bug.png (or virtually any logo area with odd x and y and even width and height.) The right and bottom chroma borders (in green) are clearly off. In order to fix this, the width and height must be adjusted to include the bits lost in the rounding of the left and top border positions, respectively, prior to being themselves rounded up.

* | lavfi/delogo: take SAR into accountJean Delvare2013-07-03
| | | | | | | | | | | | | | | | | | | | | | When interpolating, weights are based on relative distances, which assume square pixels. If a non-1:1 sample aspect ratio is used, it should be taken into account when comparing distances, because the human eye and brain care about the picture as it is displayed, not stored.

* | lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at ↵Stefano Sabatini2013-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the next bump Add function avfilter_graph_parse_ptr() and favor it in place of avfilter_graph_parse(), which will be restored with the old/Libav signature at the next bump. If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the Libav-compatible signature for avfilter_graph_parse(). At the next major bump the current implementation of avfilter_graph_parse() should be dropped in favor of the Libav/old implementation. Should address trac ticket #2672.
* | lavfi/delogo: use weighted interpolationJean Delvare2013-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original delogo algorithm interpolates both horizontally and vertically and uses the average to compute the resulting sample. This works reasonably well when the logo area is almost square. However when the logo area is significantly larger than high or higher than large, the result is largely suboptimal. The issue can be clearly seen by testing the delogo filter with a fake logo area that is 200 pixels large and 2 pixels high. Vertical interpolation gives a very good result in that case, horizontal interpolation gives a very bad result, and the overall result is poor, because both are given the same weight. Even when the logo is roughly square, the current algorithm gives poor results on the borders of the logo area, because it always gives horizontal and vertical interpolations an equal weight, and this is suboptimal on borders. For example, in the middle of the left hand side border of the logo, you want to trust the left known point much more than the right known point (which the current algorithm already does) but also much more than the top and bottom known points (which the current algorithm doesn't do.) By properly weighting each known point when computing the value of each interpolated pixel, the visual result is much better, especially on borders and/or for high or large logo areas. The algorithm I implemented guarantees that the weight of each of the 4 known points directly depends on its distance to the interpolated point. It is largely inspired from the original algorithm, the key difference being that it computes the relative weights globally instead of separating the vertical and horizontal interpolations and combining them afterward.
