ImageInstanceQ
✖
ImageInstanceQ
gives True if image appears to be an instance of the object obj, and gives False otherwise.
Details and Options
- ImageContainsQ tries to identify whether an image is an instance of a given category.
- Possible forms for both object obj and category cat are:
-
"type" entity type, as used in Interpreter "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 instance1instance2… any of the instancei - The following options can be given:
-
AcceptanceThreshold 0.5 what recognition probability to require PerformanceGoal Automatic favor algorithms with specific advantages RecognitionPrior 0.5 prior probability for a True result TargetDevice "CPU" the target device on which to compute - ImageInstanceQ uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
- ImageInstanceQ may download resources that will be stored in your local object store at $LocalBase, and can be listed using LocalObjects[] and removed using ResourceRemove.

AcceptanceThreshold (1)
Using the default AcceptanceThreshold, an object may not be identified:
