  • Declaration

    Objective-C

    - (double)getClipLimit NS_SWIFT_NAME(getClipLimit());

    Swift

    func getClipLimit() -> Double

  • Equalizes the histogram of a grayscale image using Contrast Limited Adaptive Histogram Equalization.

    Declaration

    Objective-C

    - (void)apply:(nonnull Mat *)src dst:(nonnull Mat *)dst;

    Swift

    func apply(src: Mat, dst: Mat)

    Parameters

    src

    Source image of type CV_8UC1 or CV_16UC1.

    Destination image.

  • Declaration

    Objective-C

    - (void)collectGarbage NS_SWIFT_NAME(collectGarbage());

    Swift

    func collectGarbage()

  • Sets threshold for contrast limiting.

    Declaration

    Objective-C

    - (void)setClipLimit:(double)clipLimit;
