Extract image 3d values

Doubles =	extractImg3dValues (inImg3d,inCoords3dColl)
Doubles =	extractImg3dValues (inImg3d,inCoords3dColl,inOptInterpolationPolicy)
Doubles =	extractImg3dValues (inImg3d,inCoords3dColl,inOptInterpolationPolicy,inOptImageValueExtractionMethod)

Detailed Description

extract values at specific coordinates from a 3d image

This algorithm allows to extract grey level values from an input 3d image.

If input image is a multi volume image (ie. sequence or color image), each plane is processed separatly.

Given a collection of input 3d coordinates , algorithm extracts an associated collection of grey level values from input image . User can specify an optional interpolation policy (see enumerate ipsdk::imaproc::attr::eInterpolationPolicy) used to extract values from image.

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLUtility as util

Code Example

    # opening of input image
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath)
    
    # create a coordinates collection
    inCoordsColl = PyIPSDK.createCoords3dColl()
    inCoordsColl.addCoords(50.1, 50.7, 30.2)
    inCoordsColl.addCoords(75.6, 75.8, 41.0)
    inCoordsColl.addCoords(120.1, 90.4, 10.9)
    
    # retrieve associated grey values into image with default interpolation policy
    outGreyValues1 = util.extractImg3dValues(inImg, inCoordsColl)
    for i in range(0, len(inCoordsColl.coll)):
        print("Grey value at {" + str(inCoordsColl.coll[i].x) + ", " +
                                  str(inCoordsColl.coll[i].y) + ", " +
                                  str(inCoordsColl.coll[i].z) + "} = " +
                                  str(outGreyValues1.coll[i]))
                                  
    # retrieve associated grey values into image with cubic interpolation policy
    outGreyValues2 = util.extractImg3dValues(inImg, inCoordsColl, PyIPSDK.eInterpolationPolicy.eIP_Cubic)
    for i in range(0, len(inCoordsColl.coll)):
        print("Grey value at {" + str(inCoordsColl.coll[i].x) + ", " +
                                  str(inCoordsColl.coll[i].y) + ", " +
                                  str(inCoordsColl.coll[i].z) + "} = " +
                                  str(outGreyValues2.coll[i]))
