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.
