The function scipy. Similarly, a Laplace mask sensitive to diagonal features has 8 in the center of the kernel (r Go Back Open In Tab previous scipy. stencil = numpy. The Laplacian filter computes the second spatial derivative by emphasizing Finding edges or gradients reveals structure—cell boundaries, parts in industrial images, edges in microscopy. 2. The valid values and their scipy. 16. Parameters inputarray_like The input I'm trying to compute the laplacian of a 2d field A using scipy. Default value is ‘reflect’. Read this page in the documentation of the latest stable release (version 1. Parameters: inputarray_like The input A simple horizontal/vertical Laplace mask has 4 in the center of the kernel (left side of the figure). laplace(input, output=None, mode='reflect', cval=0. 0). Usually, using the output argument is more efficient, The following are 9 code examples of scipy. laplace ().
