MLKitSegmentationCommon Framework Reference

  • MLKSegmentationMask represents the result of a segmentation operation, providing a mask to identify segmented regions within an image.

  • The buffer property offers a CVPixelBuffer containing per-pixel region values ranging from 0.0 to 1.0, where 1.0 signifies inclusion within the segmented area.

  • While the MLKSegmentationMask owns and manages the lifecycle of the buffer, external users can retain it using CVPixelBufferRetain() for extended usage.

MLKSegmentationMask


@interface MLKSegmentationMask : NSObject

The result from a segmenter operation.

  • The segmentation buffer for the mask.

    The buffer will be of format typekCVPixelFormatType_OneComponent32Float. Each pixel in the mask will have a value in range [0.0f, 1.0f] where 1 indicates that a pixel is inside the segmented region, and 0 indicates that a pixel is outside the segmented region. Callers may query the mask for per-pixel region-value estimates, but are responsible for defining their own threshold for intermediate values. The buffer is owned by the SegmentationMask and will be released when the container is deallocated, unless callers explicitly maintain a reference to it via CVPixelBufferRetain().
