Filtres (1D / 2D)

Convolve signals ou images avec editable NxN kernels (gauss, sobel, LoG, ...)

About this tool

1D: convolve a preset or file-loaded signal with an editable kernel; the chart shows input and result. 2D: matrix of input values (or image / text), N×N kernel with presets (box, Gaussian, Sobel, Laplacian, LoG, sharpen, emboss). Input values / Output values text areas mirror the numeric grids; border handling is edge replication.
