# Create list of axes for easy iteration. Basically, I want to loop over all frames of video, subtract each frame from background image and display the result i.e subtractedImg either using subplot or figure. Num_rows = int(num_images / num_cols) + (1 if num_images % num_cols != 0 else 0)įig, axes = plt.subplots(num_rows, num_cols, figsize=figsize) If None, then cmap will beĪssert isinstance(list_images, np.ndarray)Īssert len(list_images) = len(list_titles), '%d imgs != %d titles' % (len(list_images), len(list_titles))Īssert len(list_images) = len(list_cmaps), '%d imgs != %d cmaps' % (len(list_images), len(list_cmaps)) imshow siempre muestra una imagen en la figura actual. MATLAB no restringe el nmero de imgenes que puede mostrar de forma simultnea. La forma ms sencilla de mostrar varias imgenes al mismo tiempo es hacerlo en ventanas de figuras separadas. Optional list of cmap values for each image. Mostrar varias imgenes en distintas ventanas de figuras. Optional list of titles to be shown for each image. p determines where you want to place your plot within the grid. You can place plots within a m x n grid, where m contains the number of rows and n contains the number of columns in your figure. subplot places multiple figures within the same window. Shows a grid of images, where each image is a Numpy array. You have three numbers that are used within subplot. If (c1 = c2).all() and (c2 = c3).all():ĭef show_image_list(list_images, list_titles=None, list_cmaps=None, grid=True, num_cols=2, figsize=(20, 10), title_fontsize=30): # Check the color channels to see if they're all the same.Ĭ1, c2, c3 = img, img, img Here's the code: import matplotlib.pyplot as plt We start by drawing the original image in the first quadrant of the figure, and then drawing each successive downsampled image in a smaller quadrant: im imread ('autumn.tif') im1 im (1:206,1:206,:) make the image square for demonstration purposes im2 imresize (im1,0.5) im3 imresize (im2,0.5) subplot ('position', 1-1. You can omit the parentheses and specify subplot as. subplot(1,1,1) or clf deletes all axes objects and returns to the default subplot(1,1,1) configuration. Pass in a list of images, a list of titles for each image, and other arguments. However, if the subplot specification exactly matches the position of an existing axes, then the matching axes is not deleted and it becomes the current axes.Show_image_list(list_images, figsize=(10, 10)) It will also infer if each image is color or grayscale. It will create a grid with 2 columns by default. The first two arguments define the number of rows and columns that will be included in the grid. The basic form of the subplot() command takes in three inputs: nRows, nCols, linearIndex.
