Detailed Description

computation of the square root of an image

On output image values are given by:

Input and output images must have same size. Input and output types must be real32.

Attributes description

Attribute description for algorithm :

Name	ToolTip	Default Initializer
ipsdk::imaproc::attr::InRealImg	[Input] image for processing operation (data contained in image buffer are reals)	X
ipsdk::imaproc::attr::OutImg	[Output] image for processing operation	ipsdk::imaproc::duplicateInOut (_pOutImg, _pInRealImg)

Global Rule description

Global rule description for algorithm :
ipsdk::imaproc::matchSize (_pInRealImg,_pOutImg)

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLArithmetic as arithm

Code Example

    # opening of input image
    geometry = PyIPSDK.geometry2d(PyIPSDK.eImageBufferType.eIBT_Real32, 510, 509)
    inImg = PyIPSDK.loadRawImageFile(inputImgPath, geometry)
    
    # computation of image square root
    outImg = arithm.sqrtImg(inImg)

Code Example

        // open input image
        ImageGeometryPtr pImageGeometry = geometry2d(image::eImageBufferType::eIBT_Real32, sizeX, sizeY);
        ImagePtr pInImg = loadRawImageFile(inputImgPath, *pImageGeometry);

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

        // compute subtraction for input image
        ImagePtr pAutoOutImg = sqrtImg(pInImg);

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

        // create output image
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pImageGeometry);

        // compute square root of input image
        sqrtImg(pInImg, pOutImg);
