skimage¶. skimage. Image Processing for Python. scikit-image (a.k.a. skimage) is a collection of algorithms for image processing and computer vision. The main package of skimage only provides a few utilities for converting between image data types; for most features, you need to import one of the following subpackages:

downscale_local_mean¶ skimage.transform. downscale_local_mean (image, factors, cval = 0, clip = True) [source] ¶ Down-sample N-dimensional image by local averaging. The image is padded with cval if it is not perfectly divisible by the integer factors.. In contrast to interpolation in skimage.transform.resize and skimage.transform.rescale this function calculates the local …

@Decker skimage.transform.resize provides some control via the 'order'-parameter. order=0 is nearest neighbour, 1=bi-linear, 2=bi-quadratic, 3=bi-cubic etc. No area mean or lanczos interpolation however. –

31.10.2018 · I have a 4D np.array size (10000,32,32,3) that represents a set of 10000 RGB images. How can I use skimage.transform.resize or other function to resize all …

Rescale, resize, and downscale¶. Rescale, resize, and downscale. Rescale operation resizes an image by a given scaling factor. The scaling factor can either be a single floating point value, or multiple values - one along each axis. Resize serves the same purpose, but allows to specify an output image shape instead of a scaling factor.

>>> from skimage import data >>> from skimage.transform import rotate >>> image = data. camera >>> rotate (image, 2). shape (512, 512) >>> rotate (image, 2, resize = True). shape (530, 530) >>> rotate (image, 90, resize = True). shape (512, 512)

Dec 11, 2015 · skimage.transform.resizecalls a function wrap(_warps.py#L161) which always converts an input image to float64(_warps.py#L797).
