## Pages in this subsection

- [Image Processing](index.html.md): Index of eVision Image Processing sample programs covering ROI display, filtering, color components, HDR fusion, and eGrabber bridging.
- [Basic](basic.html.md): Shows how to load and display an image and graphically create, position, and drag an ROI on it using eVision's basic API.
- [BasicWPF](basicwpf.html.md): Demonstrates displaying an image and graphically interacting with an ROI within a WPF application using eVision.
- [ConsoleBasic](consolebasic.html.md): Shows how to initialize and release the eVision library, check for a license, and load and process an image from the console.
- [Region](region.html.md): Shows how to create an ERegion of various shapes and use it to restrict eVision image processing to a specific domain.
- [RegionFreeHand](regionfreehand.html.md): Demonstrates creating a freehand ERegion by painting with a brush shape using the ERegionFreeHandPainter.
- [EasyImageFilter](easyimagefilter.html.md): Demonstrates loading an image and applying filter operations, such as erosion and opening, to it using EasyImage.
- [FourierFiltering](fourierfiltering.html.md): Demonstrates computing the direct and inverse Fourier transform of a grayscale image and applying a frequency-domain mask with EasyImage.
- [EasyColorComponent](easycolorcomponent.html.md): Demonstrates converting a color image from RGB to another color space, such as ISH, and retrieving a single component with EasyColor.
- [EasyHDRFusion](easyhdrfusion.html.md): Shows how to perform HDR fusion on a set of color images with different exposure times using EasyImage's merger and tone-mapper algorithms.
- [EGrabberBridge](egrabberbridge.html.md): Shows how to import images produced by an eGrabber buffer into eVision using the EGrabberBridge, making them compatible with all tools.
- [SharedLibraryConsole](sharedlibrary.html.md): Shows how to combine a command-line program and a shared library in a single CMake project and manually initialize eVision within it.

## Optional
