Description

hamming_change_regionhamming_change_regionhamming_change_regionHammingChangeRegionHammingChangeRegion changes the region in the left upper part of the image given by WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight such that the resulting regions have a Hamming distance of DistanceDistanceDistanceDistancedistance to the input regions. This is done by adding or removing DistanceDistanceDistanceDistancedistance points from the input region.

Attention

If WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight are chosen too large the resulting region requires a lot of memory.

Parameters

InputRegionInputRegionInputRegionInputRegioninputRegion (input_object)  region(-array) → objectHRegionHRegionHRegionXHobject

Region to be modified.

OutputRegionOutputRegionOutputRegionOutputRegionoutputRegion (output_object)  region(-array) → objectHRegionHRegionHRegionXHobject *

Regions having the required Hamming distance.

WidthWidthWidthWidthwidth (input_control)  extent.x → HTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong)

Width of the region to be changed.

Default value: 100

Suggested values: 64, 128, 256, 512

Typical range of values: 1 ≤ Width Width Width Width width ≤ 512 (lin)

Minimum increment: 1

Recommended increment: 10

Restriction: Width > 0

HeightHeightHeightHeightheight (input_control)  extent.y → HTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong)

Height of the region to be changed.

Default value: 100

Suggested values: 64, 128, 256, 512

Typical range of values: 1 ≤ Height Height Height Height height ≤ 512 (lin)

Minimum increment: 1

Recommended increment: 10

Restriction: Height > 0

DistanceDistanceDistanceDistancedistance (input_control)  integer → HTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong)

Hamming distance between the old and new regions.

Default value: 1000

Suggested values: 100, 500, 1000, 5000, 10000

Typical range of values: 0 ≤ Distance Distance Distance Distance distance ≤ 10000 (lin)

Minimum increment: 1

Recommended increment: 10

Restriction: (Distance >= 0) && (Distance < (Width * Height))

Complexity

Memory requirement of the generated region (worst case): O(2 * WidthWidthWidthWidthwidth * HeightHeightHeightHeightheight).

Result

hamming_change_regionhamming_change_regionhamming_change_regionHammingChangeRegionHammingChangeRegion 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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
