WitrynaFit Gaussian Naive Bayes according to X, y. Parameters: Xarray-like of shape (n_samples, n_features) Training vectors, where n_samples is the number of samples and n_features is the number of features. yarray-like of shape (n_samples,) Target values. sample_weightarray-like of shape (n_samples,), default=None. Witryna8 sty 2013 · The input image is a noisy image. In the first case, global thresholding with a value of 127 is applied. In the second case, Otsu's thresholding is applied directly. In the third case, the image is first filtered with a 5x5 gaussian kernel to remove the noise, then Otsu thresholding is applied. See how noise filtering improves the result.

WitrynaMulti-dimensional Gaussian filter. Parameters: image array-like. Input image (grayscale or color) to filter. sigma scalar or sequence of scalars, optional. Standard deviation for Gaussian kernel. The standard deviations of the Gaussian filter are given for each axis as a sequence, or as a single number, in which case it is equal for all axes.
