Image Processing ​

VTK's image processing capabilities for 2D and 3D image data.

Image Data in VTK ​

  • vtkImageData structure and organization
  • Pixel types and data ranges
  • Image coordinate systems (origin, spacing, extent)
  • Multi-component images

Basic Operations ​

  • Arithmetic operations (add, subtract, multiply)
  • Thresholding and segmentation
  • Histogram computation and equalization
  • Windowing and leveling for display

Filtering ​

  • Gaussian smoothing and noise reduction
  • Edge detection (Sobel, Canny)
  • Morphological operations (erosion, dilation, opening, closing)
  • Convolution with custom kernels
  • Median filtering

Advanced Operations ​

  • Image registration and resampling
  • Connected component labeling
  • Distance transforms
  • Fourier transforms and frequency domain filtering

Topics Covered ​

  • Working with medical image data (DICOM)
  • Multi-planar reformatting (MPR)
  • Image interpolation methods
  • Batch processing of image stacks
