hamming_change_region(InputRegion : OutputRegion : Width, Height, Distance : )

描述

hamming_change_regionhamming_change_regionHammingChangeRegionHammingChangeRegionHammingChangeRegionhamming_change_region changes the region in the left upper part of the image given by WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight such that the resulting regions have a Hamming distance of DistanceDistanceDistanceDistancedistancedistance to the input regions. This is done by adding or removing DistanceDistanceDistanceDistancedistancedistance points from the input region.

注意

If WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight are chosen too large the resulting region requires a lot of memory.

执行信息

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.

参数

InputRegionInputRegionInputRegionInputRegioninputRegioninput_region (input_object) region(-array) → object

Region to be modified.

OutputRegionOutputRegionOutputRegionOutputRegionoutputRegionoutput_region (output_object) region(-array) → object

Regions having the required Hamming distance.

WidthWidthWidthWidthwidthwidth (input_control) extent.x → (integer)

Width of the region to be changed.

默认值： 100

建议值： 64, 128, 256, 512

值范围： 1 ≤ Width Width Width Width width width ≤ 512 (lin)

最小增量： 1

建议增量： 10

限制： Width > 0

HeightHeightHeightHeightheightheight (input_control) extent.y → (integer)

Height of the region to be changed.

默认值： 100

建议值： 64, 128, 256, 512

值范围： 1 ≤ Height Height Height Height height height ≤ 512 (lin)

最小增量： 1

建议增量： 10

限制： Height > 0

DistanceDistanceDistanceDistancedistancedistance (input_control) integer → (integer)

Hamming distance between the old and new regions.

默认值： 1000

建议值： 100, 500, 1000, 5000, 10000

值范围： 0 ≤ Distance Distance Distance Distance distance distance ≤ 10000 (lin)

最小增量： 1

建议增量： 10

限制： Distance >= 0 && Distance < Width * Height

Complexity

Memory requirement of the generated region (worst case): O(2 * WidthWidthWidthWidthwidthwidth * HeightHeightHeightHeightheightheight).

结果

hamming_change_regionhamming_change_regionHammingChangeRegionHammingChangeRegionHammingChangeRegionhamming_change_region returns 2 ( H_MSG_TRUE) if all parameters are correct. The behavior in case of empty input (no regions given) can be set via set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
