名称
sp_distributionT_sp_distributionSpDistributionSpDistributionsp_distribution — 生成椒盐噪声分布。Sp：salt and pepper。
签名
描述
sp_distributionsp_distributionSpDistributionSpDistributionSpDistributionsp_distribution generates a noise distribution with the
values 0 and 255. The parameters PercentSaltPercentSaltPercentSaltPercentSaltpercentSaltpercent_salt and
PercentPepperPercentPepperPercentPepperPercentPepperpercentPepperpercent_pepper determine the percentage of white and black
noise pixels, respectively. The sum of these parameters must be
smaller than 100. Usually, the result DistributionDistributionDistributionDistributiondistributiondistribution is
used as input for the operator add_noise_distributionadd_noise_distributionAddNoiseDistributionAddNoiseDistributionAddNoiseDistributionadd_noise_distribution。
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）。
- 未采用并行化处理。
