yolov3 detect image

https://www.mathworks.com/help/vision/ug/object-detection-using-yolo-v3-deep-learning.html

I am useing the yolov3 detect sample

i want to detect my image but have some problem

it seems not match the yolov3Detect Xtest type

please helpe me

aaaa=imread('vehicleImage.jpg');

% Convert to dlarray.

aaaa=single(aaaa);

XTest = dlarray(aaaa, 'SSCB');

executionEnvironment = "auto";

[bboxes, scores, labels] = yolov3Detect(net, XTest, networkOutputs, anchorBoxes, anchorBoxMasks, confidenceThreshold, overlapThreshold, classNames);

clear yolov3Detect

if ~isempty(scores{1})

I = insertObjectAnnotation(aaaa, 'rectangle', bboxes{1}, scores{1});

end

figure('Name','detect')

imshow(I)

[Isee You]

i = imread(fullFileName);

confidenceThreshold = 0.7;

overlapThreshold = 0.5;

i=imresize(i,networkInputSize(1:2));

i=im2single(i);

XTest = dlarray(i,'SSCB');

if (executionEnvironment == "auto" && canUseGPU) || executionEnvironment == "gpu"

XTest = gpuArray(XTest);

end

[bboxes, scores, labels] = yolov3Detect(net, XTest, networkOutputs, anchorBoxes,anchorBoxMasks, confidenceThreshold, overlapThreshold, classNames);
