Class NullModel

java.lang.Object

org.photonvision.vision.objects.NullModel

All Implemented Interfaces:

Model, ObjectDetector, Releasable

public class NullModel
extends Object
implements Model, ObjectDetector

A 'null' implementation of the Model and ObjectDetector interfaces. This is used when no model is available to load.

detect

public List<NeuralNetworkPipeResult> detect(org.opencv.core.Mat in,
 double nmsThresh,
 double boxThresh)

Description copied from interface: ObjectDetector

Detects objects in the given input image. Preprocessing and postprocessing steps should be embedded into this call.

Specified by:

detect in interface ObjectDetector

Parameters:

in - The input image to perform object detection on.

nmsThresh - The threshold value for non-maximum suppression.

boxThresh - The threshold value for bounding box detection.

Returns:

A list of NeuralNetworkPipeResult objects representing the detected objects. Returns an empty list if the detector is not initialized or if no objects are detected.
