描述

该算子 hamming_distance_normhamming_distance_normHammingDistanceNormHammingDistanceNormHammingDistanceNormhamming_distance_norm returns the hamming distance between two regions, i.e., the number of pixels of the regions which are different (DistanceDistanceDistanceDistancedistancedistance). Before calculating the difference the region in Regions1Regions1Regions1Regions1regions1regions_1 is normalized onto the regions in Regions2Regions2Regions2Regions2regions2regions_2. The result is the number of pixels contained in one region but not in the other: The parameter SimilaritySimilaritySimilaritySimilaritysimilaritysimilarity describes the similarity between the two regions based on the hamming distance DistanceDistanceDistanceDistancedistancedistance:

The following types of normalization are available:

'center'"center""center""center""center""center":

The region is moved so that both regions have the save center of gravity.

If both regions are empty SimilaritySimilaritySimilaritySimilaritysimilaritysimilarity is set to 0. The regions with the same index from both input parameters are always compared.

注意

In both input parameters the same number of regions must be passed.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 在元组级别自动并行化。

参数表

Complexity

If F is the area of a region the mean runtime complexity is O(sqrt(F)).

结果

hamming_distance_norm 返回值 2 ( H_MSG_TRUE) if the number of objects in both parameters is the same and is not 0. The behavior in case of empty input (no input objects available) is set via 该算子 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>). The behavior in case of empty region (the region is the empty set) is set via set_system('empty_region_result',<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>). If necessary an exception is raised.
