SegmentationMask class - face_detection_tflite library

Constructors

SegmentationMask({required Float32List data, required int width, required int height, required int originalWidth, required int originalHeight, List<double> padding = const [0.0, 0.0, 0.0, 0.0]}): Creates a segmentation mask with validation.
factory
SegmentationMask.fromMap(Map<String, dynamic> map): Creates a SegmentationMask from a serialized map.
factory
SegmentationMask.internal({required Float32List internalData, required int width, required int height, required int originalWidth, required int originalHeight, required List<double> padding}): Internal const constructor that accepts already-validated buffers.
const

data → Float32List: Returns a defensive copy of the raw probability data (row-major).
no setter
hashCode → int: The hash code for this object.
no setterinherited
height → int: Mask height in pixels.
final
internalData → Float32List: Raw float32 mask data; access via data (defensive copy) or at.
final
originalHeight → int: Original source image height.
final
originalWidth → int: Original source image width.
final
padding → List<double>: Padding [top, bottom, left, right] applied during letterboxing.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
width → int: Mask width in pixels.
final

at(int x, int y) → double: Returns probability at (x, y) in mask coordinates. Out-of-bounds → 0.0.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toBinary({double threshold = 0.5}) → Uint8List: Converts to binary mask (0 or 255) using threshold.
toMap() → Map<String, dynamic>: Serialization for isolate transfer.
toRgba({int foreground = 0xFFFFFFFF, int background = 0x00000000, PixelFormat format = PixelFormat.rgba, double threshold = 0.5}) → Uint8List: Converts to RGBA image with configurable colors.
toString() → String: A string representation of this object.
override
toUint8() → Uint8List: Converts to 8-bit grayscale mask (0-255).
upsample({int? targetWidth, int? targetHeight, int maxSize = 2048}) → SegmentationMask: Upsamples mask to target dimensions using bilinear interpolation.
