image = getROI3dImg (inImg,xOffset,yOffset,zOffset,xSz,ySz,zSz)

Detailed Description

Algorithm allowing to copy a 3d ROI of an image.

This algorithm allows to copy the region of interest, delimited by a 3d box, of an image.
The box is defined by the 2 attributes InInputImg3dOffset and InOutputImg3dSize.
Output image type is the same as input.
Size of output image is given by the InOutputImg3dSize attribute.

On output image, values are given by :

$OutImg[x, y, z] = InROIImg[x-InInputImg3dOffset::XOffset, y-InInputImg3dOffset::YOffset, z-InInputImg3dOffset::ZOffset]$

with:

$x \in$ [ .. ]
$y \in$ [ .. ]
$z \in$ [ .. ]

Example of Python code :

Example imports

import PyIPSDK

import PyIPSDK.IPSDKIPLUtility as util

Code Example

    # opening of input image
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath)
    
    # 3d ROI extraction
    outImg = util.getROI3dImg(inImg, 10, 11, 12, 19, 20, 21)

Code Example

        ImagePtr pInImg = loadTiffImageFile(inputImgPath, eTiffDirectoryMode::eTDM_Volume);
        if(pInImg->getBufferType() != imageBufferType)
            pInImg = convertImg(pInImg, imageBufferType);
        ImageGeometryPtr pOutImageGeometry = geometry3d(imageBufferType, outSizeX, outSizeY, outSizeZ);
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pOutImageGeometry);
        // ROI extraction of image
        getROI3dImg(pInImg, inOffsetX, inOffsetY, inOffsetZ, outSizeX, outSizeY, outSizeZ, pOutImg);
