Pixel based filters — SciPy Filters for QGIS

Complete pixel statistics

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelMinMaxMeanAlgorithm

Complete pixel statistics

Returns min, max, mean, median and std of all bands for each individual pixel

Difference band to band

class scipy_filters.algs.gradient_algorithm.SciPyPixelDiffAlgorithm

Difference band to band

Returns band to band difference for each pixel, calculated with numpy.diff.

The number of bands in the output is the number of input bands minus one.

Return absolute values Difference is calculated band to band, starting with band 1. The result contains also negative values, optionally the absolute values are returned.

Pixel gradient filter

class scipy_filters.algs.gradient_algorithm.SciPyPixelGradientAlgorithm

Pixel gradient filter

Returns band to band gradient for each pixel, calculated with numpy.gradient.

Return absolute values Gradient is calculated band to band, starting with band 1. The result contains also negative values, optionally the absolute values are returned.

Pixel maximum filter

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelMaxAlgorithm

Pixel Statistics Maximum Filter

Returns maximum of all bands for each individual pixel

Pixel mean filter

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelMeanAlgorithm

Pixel Statistics Mean Filter

Returns mean of all bands for each individual pixel

Pixel median filter

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelMedianAlgorithm

Pixel Statistics Median Filter

Returns mean of all bands for each individual pixel

Pixel minimum filter

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelMinAlgorithm

Pixel Statistics Minimum Filter

Returns minimum of all bands for each individual pixel

Pixel range filter

class scipy_filters.algs.scipy_pixel_statistic_algorithms.SciPyPixelRangeAlgorithm
