gives an association of lists of bounding boxes for each identified category of objects in image.
gives a list of bounding boxes for subimages identified as an instance of the specified category.
Details and Options
- ImageBoundingBoxes attempts to find instances of an object category present in an image and returns a list of bounding boxes per category given as Rectangle objects.
- Coordinates are assumed to be in the standard image coordinate system.
- Possible forms for category include:
"concept" named concept, as used in "Concept" entities "word" English word, as used in WordData wordspec word sense specification, as used in WordData Entity[…] any appropriate entity category1|category2|… any of the categoryi
- The following options can be given:
AcceptanceThreshold Automatic identification acceptance threshold MaxFeatures Automatic maximum number of subimages to return MaxOverlapFraction Automatic maximum bounding box overlap TargetDevice "CPU" the target device on which to compute
- ImageBoundingBoxes uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
- ImageBoundingBoxes may download resources that will be stored in your local object store at $LocalBase, and can be listed using LocalObjects and removed using ResourceRemove.
