collapse all in page

Syntax

detector = peopleDetectorACF
detector = peopleDetectorACF(name)

Description

detector = peopleDetectorACF returns a pretrained upright people detector using aggregate channel features (ACF). The detector is an acfObjectDetector object, and is trained using the INRIA person data set.

example

detector = peopleDetectorACF(name) returns a pretrained upright people detector based on the specified model name.

Examples

Open Live Script

Load the upright people detector.

detector = peopleDetectorACF;

Read an image. Detect people in the image.

I = imread('visionteam1.jpg');
[bboxes,scores] = detect(detector,I);

Annotate detected people with bounding boxes and their detection scores.

I = insertObjectAnnotation(I,'rectangle',bboxes,scores);
figure
imshow(I)
title('Detected People and Detection Scores')

Figure contains an axes object. The hidden axes object with title Detected People and Detection Scores contains an object of type image.

Input Arguments

ACF classification model, specified as 'inria-100x41' or 'caltech-50x21'. The 'inria-100x41' model was trained using the INRIA Person data set. The 'caltech-50x21' model was trained using the Caltech Pedestrian data set.

Output Arguments
