OTB.BandMathX: This application performs mathematical operations on several multiband images.

{"id": "OTB.BandMathX", "title": "This application performs mathematical operations on several multiband images.", "description": "This application performs a mathematical operation on several multi-band images and outputs the result into an image (multi- or mono-band, as opposed to the BandMath OTB-application). The mathematical formula is done by the muParserX library.The list of features and the syntax of muParserX is available at [1].As opposed to muParser (and thus the BandMath OTB-application [2]), muParserX supports vector expressions which allows outputting multi-band images.Hereafter is a brief reference of the muParserX syntaxFundamentals------------The formula can be written using:* numerical values ( 2.3, -5, 3.1e4, ...)* variables containing pixel values (please, note the indexing of inputs from 1 to N). Examples for the first input image: * ``im1`` a pixel from 1st input, made of n components (n bands) * ``im1b2`` the 2nd component of a pixel from 1st input (band index is 1-based) * ``im1b2N3x4`` a 3x4 pixels Neighbourhood of a pixel the 2nd component of a pixel from the 1st input * ``im1PhyX`` horizontal (X-axis) spacing of the 1st input. * ``im1PhyY`` vertical (Y-axis) spacing of the 1st input input. * ``im1b2Mean`` mean of the 2nd component of the 1st input (global statistics) * ``im1b2Mini`` minimum of the 2nd component of the 1st input (global statistics) * ``im1b2Maxi`` maximum of the 2nd component of the 1st input (global statistics) * ``im1b2Sum`` sum of the 2nd component of the 1st input (global statistics) * ``im1b2Var`` variance of the 2nd component of the 1st input (global statistics) * ``idxX`` and ``idxY`` are the indices of the current pixel (generic variables)* binary operators: * ``+`` addition, ``-`` subtraction, ``*`` multiplication, ``/`` division * ``^`` raise x to the power of y * ``", "version": "1.0.0", "jobControlOptions": ["sync-execute", "async-execute", "dismiss"], "outputTransmission": ["value", "reference"], "links": [{"rel": "execute", "type":
