image =

genericSubtractImgImg (inImg1,inImg2)

Detailed Description

Subtract images with different dimensions.

Subtraction of 2 images with different dimensions (volume with plan, volume color with volume...). The image with the highest dimensions is always have to be the first one.

The output image values are given by:

See Addition between images with different dimensions for illustrated example.

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLArithmetic as arithm

Code Example

    # opening input images
    inGeometry = PyIPSDK.geometry2d(PyIPSDK.eImageBufferType.eIBT_UInt8, 510, 509)
    inImg1 = PyIPSDK.loadTiffImageFile(inputImg1Path)
    inImg2 = PyIPSDK.loadTiffImageFile(inputImg2Path)

    # images subtraction
    outImg = arithm.genericSubtractImgImg(inImg1, inImg2)

Code Example

        // open input images with different dimensions (3d and 2d in this case)
        ImageGeometryPtr pInputImageGeometry1 = geometry3d(inType, sizeX, sizeY, sizeZ);
        ImagePtr pInImg1 = loadRawImageFile(in1Path, *pInputImageGeometry1);
        ImageGeometryPtr pInputImageGeometry2 = geometry2d(inType, sizeX, sizeY);
        ImagePtr pInImg2 = loadRawImageFile(in2Path, *pInputImageGeometry2);

        // Compute subtraction of input images
        ImagePtr pOutImgAuto = genericSubtractImgImg(pInImg1, pInImg2);

        // Or create output image with the same dimensions than the first image
        ImageGeometryPtr pOutputImageGeometry = geometry3d(inType, sizeX, sizeY, sizeZ);
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pOutputImageGeometry);

        // compute subtraction of input images
        genericSubtractImgImg(pInImg1, pInImg2, pOutImg);
