LocalStatisticExtraction

在输入图像的选定通道中的每个像素上计算局部统计矩

描述

这个应用程序在指定的邻域内,对输入图像的选定通道中的每个像素计算4个局部统计矩。输出图像是多波段的,每个波段有一个统计矩(特征)。因此,4个输出特征是均值、方差、偏度和峰度。它们在输出图像中按此顺序提供。

参数

Input Image -in image Mandatory
The input image to compute the features on.

Feature Output Image -out image [dtype] Mandatory
Output image containing the local statistical moments.

Selected Channel -channel int Default value: 1
The selected channel index (1 based)

Neighborhood radius -radius int Default value: 3
The computational window radius.

Available RAM (MB) -ram int Default value: 256
Available memory for processing (in MB).

实例

从命令行执行以下操作:

otbcli_LocalStatisticExtraction -in qb_RoadExtract.tif -channel 1 -radius 3 -out Statistics.tif

来自Python的评论:

import otbApplication

app = otbApplication.Registry.CreateApplication("LocalStatisticExtraction")

app.SetParameterString("in", "qb_RoadExtract.tif")
app.SetParameterInt("channel", 1)
app.SetParameterInt("radius", 3)
app.SetParameterString("out", "Statistics.tif")

app.ExecuteAndWriteOutput()
