8000圆000) and notice the computation time is long, you can first downsample it so the number of pixels ( m) will be lower. If you have a high-definition destination image (e.g. For large tile count, unless you need strict fair tile usage, you should go for the unfair mode and set freq_mul appropriately. It typically takes 30 seconds for 5000 tiles and 5 minutes for 10000 tiles. The high (cubic) computational complexity of the fair mode means that the computation time grows much faster with respect to the number of tiles.

Partial (~10x speed up for the nm part only) Here, n is the number of tiles (after duplication in fair mode), m is the number of pixels in the destination image, and k is the number of tiles used in the unfair mode (this is equal to your specified max_width multiplied by the aspect ratio of your destination image). The following table shows the time and space complexity of different cases. Performance, multiprocessing and GPU acceleration Time and space complexityĭifferent photomosaic making options have different computational complexity. Generally, saliency is not recommended to use on videos due to its long computational time and difficulty to tune. Python make_img.py -path img/catsdogs -dest_img img/2out.mp4 -size 20 -unfair -max_width 100 -freq_mul 2 -out v_freq_2.mp4 -gpu -video -skip_frame 2ĭo note that some options are not supported, and some options are slower than other.

Generally, a larger grid will give a better result. The height will be automatically calculated based on the max_width provided. You can also specify -max_width to change the width of the grid. Each tile in that subset will be used for an arbitrary number of times.Īdd -unfair flag to enable this option. This fitting option just selects the best subset of tiles you provided to approximate your destination tiles. Note that this recommended limit does not apply for the best fit option (see section below). Tile number larger than 6000 will probably takes longer than a minute to compute. To make sure the computation completes within a reasonable amount of time, it is recommended that you use less than 6000 tiles after duplication. For example, -dup 0.5 means only 50% of the tiles will be used, and -dup 2.5 means all tiles on average will be used 2.5 times (half of the tiles will be used 2 times and the other half will be used 3 times).

Increase that number if you don't have enough source tiles or you want a better fitting result. dup 6 specifies that each tile needs to be used 6 times (i.e. Python make_img.py -path img/zhou -dest_img examples/dest.jpg -size 25 -dup 6 -out examples/fair-dup-10.png This may happen when the number of tiles is not an integer multiple of the blocks of the destination image. This fitting option ensures that each tile is used for the same amount of times, but is the most computationally and memory intensive option.Ī few tiles might be used one more time than others. To make a photomosaic, specify the path to the destination image using -dest_img Option 2.1: Give a fair chance to each tile Note: when the tiles are a bit short to completely fill the grid, white tiles will be added. ratio 21 9 specifies the aspect ratio to be 21:9. Use -ratio w h to change the aspect ratio, whose default is 16:9. If two are specified, they are interpreted as width and height. If only one is specified, it is interpreted as the tile width and tile height will be inferred from the aspect ratios of the tiles provided (this corresponds to the infer height option in the GUI).
