image = sqrtImg (inRealImg)

Detailed Description

computation of the square root of an image

On output image values are given by:

$OutImg[i] = \begin{cases} \sqrt{InImg[i]}, & \text{if }InImg[i] \geq 0 \\ 0, & \text{otherwise} \end{cases}$

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

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)

Example of C++ code :

Header file

#include <IPSDKIPL/IPSDKIPLArithmetic/Processor/SqrtImg/SqrtImg.h>

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);
