image =

minImgImg (inImg1,inImg2)

Detailed Description

minimum of 2 images, pixel by pixel algorithm

On output image values are given by:

Input and output images must have same size.

Here is an example of a minimum operation applied to two 8-bits grey level images:

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLArithmetic as arithm

Code Example

    # opening input images
    geometry = PyIPSDK.geometry2d(PyIPSDK.eImageBufferType.eIBT_Real32, 510, 509)
    inImg1 = PyIPSDK.loadRawImageFile(inputImg1Path, geometry)
    inImg2 = PyIPSDK.loadRawImageFile(inputImg2Path, geometry)
    
    # computation of minimum of the 2 input images
    outImg = arithm.minImgImg(inImg1, inImg2)

Example of C++ code :

Header file

Code Example

        // open input images
        ImageGeometryPtr pInputImageGeometry = geometry2d(inType, sizeX, sizeY);
        ImagePtr pInImg1 = loadRawImageFile(in1Path, *pInputImageGeometry);
        ImagePtr pInImg2 = loadRawImageFile(in2Path, *pInputImageGeometry);

        // Sample with a generated output image
        // ------------------------------------

        // compute absolute value of input images
        ImagePtr pAutoOutImg = minImgImg(pInImg1, pInImg2);

        // Sample with a provided output image
        // -----------------------------------

        // create output image
        ImageGeometryPtr pOutputImageGeometry = geometry2d(outType, sizeX, sizeY);
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pOutputImageGeometry);

        // compute minimum of input images
        minImgImg(pInImg1, pInImg2, pOutImg);
