image = logicalNotImg (inBinImg)

Detailed Description

Logical not of a binary input image.

On output image values are given by:

$OutImg[i] = {\neg}(InIntImg[i])$

(with $\neg$ corresponding to the logical not operator).

Input and output images must have same size and their buffer type must be ipsdk::image::eImageBufferType::eIBT_Binary.

When the Logical not operator is applied to a binary value, the result is 1 if the input value is 0; otherwise, the result is 0.

Here is an example of a Logical not operation applied to one 2D binary image (black pixels have value 0, white pixels have value 1) :

Example of Python code :

Example imports

import PyIPSDK

import PyIPSDK.IPSDKIPLLogical as logic

Code Example

    # opening of input image
    inImg = PyIPSDK.loadTiffImageFile(inputImgPath)
    
    # logical 'not' computation
    outImg = logic.logicalNotImg(inImg)

Code Example

        // Sample with a generated output image
        // ------------------------------------
        // compute logical not for input images
         ImagePtr pAutoOutImg = logicalNotImg(pInBinImg);
        // Sample with a provided output image
        // -----------------------------------
        // create output image
        ImageGeometryPtr pOutputImageGeometry = geometry2d(eImageBufferType::eIBT_Binary, sizeX, sizeY);
        boost::shared_ptr<MemoryImage> pOutImg(boost::make_shared<MemoryImage>());
        pOutImg->init(*pOutputImageGeometry);
        // compute multiplication of input images
         logicalNotImg(pInBinImg, pOutImg);
