Imshow bw
WitrynaThe output binary image BW has values of 1 (white) for all %pixels in the input image with luminance greater than LEVEL and 0 (black) %for all other pixels. (Note that you specify LEVEL in the range [0,1], %regardless of the class of the input image.) %BW = IM2BW(I,LEVEL) converts the intensity image I to black and white. Witryna19 lis 2024 · bw_img = 1.0 - tf.image.rgb_to_grayscale(img) plt.title("Mask image with shape {}".format(bw_img.shape)) _ = plt.imshow(bw_img[...,0], cmap='gray') Play with tfa.image Mean filtering Mean filtering is a filtering technique, which is often used to remove noise from an image or signal.
