Examples for

Image Processing

Digital image processing is used in many applications, from art to forensics. Wolfram|Alpha can apply dozens of types of filters, transformations and effects to images, including methods with parameters. Apply these processes to thousands of built-in images from microscopic to telescopic.

Basic Image Processing

Scale, crop and rotate raw images or convert them to black and white or grayscale.

Crop an image:

Binarize an image:

Image Effects

Use special effects to make images look like a cartoon, oil painting or charcoal drawing or see an image through a dog's eyes.

Apply various effects to an image:

Color Processing

Perform colorization, invert colors or adjust hue, saturation and brightness. Test for accessibility for persons with visual disabilities.

Perform color processing:

Image Filtering

Apply filters or transforms to change or enhance an image. Use blurring, sharpening, filling and other convolutional filters.

Apply a filter to an image:

Apply a filter with a variable parameter:

Morphological Processing

Erode and dilate image regions. Make a skeleton graph.

Apply a morphological operator to an image:

  • Wolfram Image Computation
  • Feature Detection

    Detect edges, do image segmentation or find lines, crossings and keypoints. Use Radon and Hough transforms.

    Detect features of an image:
