描述

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.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 在元组级别上自动并行化。

参数

复杂度

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

结果

hamming_distance_norm returns the value 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 the operator 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>)。空区域（区域是空集）的情况下的可设置行为通过 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>)。如有必要，则抛出异常。
