ImageCases
ImageCases[image]
gives an association of lists of subimages for each identified category of objects in image.
ImageCases[image,category]
gives a list of subimages identified as an instance of the specified category.
ImageCases[image,categoryprop]
gives the specified property prop for each identified subimage.
ImageCases[image,{category1,category2,…}]
gives an association with lists of subimages identified as being instances of each of the categoryi.
Details and Options


- ImageCases attempts to find instances of an object category present in an image and returns a list of subimages per category.
- 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 category1category2… any of the categoryi - The property prop can be any of the following:
-
"BoundingBox" the bounding box given as a Rectangle "Dimensions" width and height of the subimage "Image" the identified subimage (default) "Position" center of the identified bounding box "Probability" probability of the identification {prop1,prop2,…} a list of properties - 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 - ImageCases uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
- ImageCases may download resources that will be stored in your local object store at $LocalBase, and can be listed using LocalObjects[] and removed using ResourceRemove.
