Transform your image to greyscale; Increase the contrast of the image by changing its minimum and maximum values. Optional: use scipy.stats.scoreatpercentile (read the docstring!) to saturate 5% of the darkest pixels and 5% of the lightest pixels.

I wish to find facets of a convex hull formed by a set of points. For this, I am using scipy.spatial.ConvexHull. The code goes as shown below. Jul 20, 2018 · Probably use the scipy._util.check_random_state function, it's copied and pasted from scikit-learn 👍 1 adbugger force-pushed the adbugger:rotation_random branch 2 times, most recently from 18848cb to c0f18bd Jul 2, 2018 The Euclidean transformation is a rigid transformation with rotation and translation parameters. The similarity transformation extends the Euclidean transformation with a single scaling factor. Parameters matrix (3, 3) array, optional. Homogeneous transformation matrix. rotation float, optional.

While special classes for rotations can be convenient, in some cases one needs rotation matrices (e.g. for working with other libraries like the affine_transform functions in scipy).
