ImageSegmentationComponents

ImageSegmentationComponents[image]

performs a global segmentation of image and returns a label matrix of components.

ImageSegmentationComponents[image,spec]

segments an image into components based on the given spec.

ImageSegmentationComponents[video,…]

segments frames of video.

Details and Options

  • ImageSegmentationComponents is a high-level image segmentation that can either segment the whole image or segment specified objects and components in an image.
  • The following specifications spec can be given:
  • possegments a component specified by an {x,y} coordinate
    {pos1,pos2,…}attempts to segment the image into components corresponding to every posi
    {{pos11,pos12,…},{pos21,…},…}specify each component with a list of positions
    Rectangle[…]specify each component with a bounding box
    {Rectangle[…],Rectangle[…],…}a list of bounding boxes, one for each component
  • When multiple positions or rectangles are provided, a segment is computed for every marker. If different markers generate significantly overlapping components, the less dominant segment will be suppressed.
  • The following options can be given:
  • PerformanceGoal Automaticaspects of performance to try to optimize
    TargetDevice"CPU"the target device on which to perform training
  • Possible settings for PerformanceGoal include:
  • Automaticautomatic tradeoff between speed and quality
    "Balanced"medium quality for average speed
    "Quality"optimize for quality of final results
    "Speed"optimize for speed of getting results

Basic Examples  (1)

Segment an image:

Wolfram Language code: ImageSegmentationComponents[[image]]//Colorize

Scope  (3)

Segment an image and colorize the segments:

Wolfram Language code: image = [image];
Wolfram Language code: lmat = ImageSegmentationComponents[image]; Colorize[lmat]

Highlight segments on the image:

Wolfram Language code: HighlightImage[image, lmat]

Generate a mask for a segment indicated by a list of positions:

Wolfram Language code: image = [image]; roi = {{45, 354}, {13, 433}, {81, 522}, {138, 438}, {186, 483}, {149, 553}};
Wolfram Language code: mask = ImageSegmentationComponents[image, roi]; Colorize[mask]

Highlight the specified target points as well as the segmentation on the image:

Wolfram Language code: HighlightImage[image, {roi, Green, Image[mask, "Bit"]}]

Generate a mask for a segment inside a bounding box:

Wolfram Language code: image = [image]; roi = Rectangle[{260, 135}, {680, 530}];
Wolfram Language code: mask = ImageSegmentationComponents[image, roi]; Colorize[mask]

Highlight the bounding box as well as the segmentation on the image:

Wolfram Language code: HighlightImage[image, {{Green, Image@mask}, {FaceForm[], EdgeForm[{Thin, Yellow}], roi}}]

Options  (1)

PerformanceGoal  (1)

By default, a medium-speed model with moderate quality is used:

Wolfram Language code: i = [image];
Wolfram Language code: ClearSystemCache[]; ImageSegmentationComponents[i]//Colorize//AbsoluteTiming

Aim for speed, but this typically results in lower quality:

Wolfram Language code: ClearSystemCache[]; ImageSegmentationComponents[i, PerformanceGoal -> "Speed"]//Colorize//AbsoluteTiming

Aim for high quality, but this typically leads to slower results:

Wolfram Language code: ClearSystemCache[];ImageSegmentationComponents[i, PerformanceGoal -> "Quality"]//Colorize//AbsoluteTiming

Applications  (3)

Segment repeating components in an image:

Wolfram Language code: ImageSegmentationComponents[[image]]//Colorize

Segment an x-ray or other image modalities:

Wolfram Language code: xray = [image];
Wolfram Language code: ImageSegmentationComponents[xray, PerformanceGoal -> "Quality"]//Colorize

Segment a region selected by points:

Wolfram Language code: pts = {{440, 308}, {335, 320}, {331, 210}, {509, 208}};
Wolfram Language code: image = [image];
Wolfram Language code: mask = ImageSegmentationComponents[image, pts];
Wolfram Language code: HighlightImage[image, {Green, Image@mask, Yellow, pts}]
