detect
(Not recommended) Detect objects using R-CNN deep learning detector
The detect
function and R-CNN object detectors are not recommended.
Use a different type of object detector instead. For more information, see Version History.
Syntax
Description
detects objects within image bboxes
= detect(detector
,I
)I
using an R-CNN (regions with
convolutional neural networks) object detector. The locations of objects detected are
returned as a set of bounding boxes.
When using this function, use of a CUDA® enabled NVIDIA® GPU is highly recommended. The GPU reduces computation time significantly. Usage of the GPU requires Parallel Computing Toolbox™. For information about the supported compute capabilities, see GPU Computing Requirements (Parallel Computing Toolbox).

also returns a categorical array of labels assigned to the bounding boxes, using either of
the preceding syntaxes. The labels used for object classes are defined during training
using the labels
