Webb30 maj 2024 · PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. It was developed by Fredrik Lundh and several other contributors. Pillow is the friendly PIL fork and an easy to use library developed by Alex Clark and other contributors. We’ll be working with Pillow. Installation: WebbWe'll use the Pillow library that we used to load the image also to resize the image. img = Image.open('../../doc/_static/stinkbug.png') img.thumbnail( (64, 64)) # resizes image in-place imgplot = plt.imshow(img) Here we use the default interpolation ("nearest"), since we did not give imshow () any interpolation argument. Let's try some others.

Webb1 dec. 2024 · So, to detect shapes we first need to analyze and understand the contours of that shape. The easiest way to do that is to use binary images (the object that we need to detect should be white and the background should be black). Hence, to detect contours we need to apply threshold or Canny edge detection. Let’s take a look at the following image. If you want to create a border around an image, something like a photo frame, you can use cv.copyMakeBorder().
