I am getting an error Reference to non-existent field 'BoundingBox'. while using the function please help

function [bboxes,flow] = findPet(frameGray, opticFlow)
% Calculate Optical Flow
flow = estimateFlow(opticFlow,frameGray);
% Threshold Image 
threshImage = ( flow.Magnitude > 4);
% Find connected components and filter regions 
[~,regions] = filterRegions(threshImage);
if(size(regions) > 0)
    bboxes = regions.BoundingBox;
else
    bboxes = [];
end
end

Are you using filterRegions from https://www.mathworks.com/matlabcentral/fileexchange/66968-image-processing-and-computer-vision-with-matlab-code-examples?focused=76fcf834-95c4-4a0e-9e5b-742862fde2a8&tab=example ?

no i am using filter regions from

the bounding box problem has been taken care of however it keeps showing an error when I try to use

function [classLabel, scores, batchTime] = cnnPredict(cnnModel,predImage,varargin)

[Copyrighted MATLAB code removed]

function im = cnnPreprocess(batchImages)
[...]
  im = imresize(im, cnnModel.net.meta.normalization.imageSize(1:2));
  im = bsxfun(@minus,im,cnnModel.net.meta.normalization.averageImage);

it shows an error in the last line as an

Reference to non-existent field 'meta'

You need to pull in the newer version of cnnPredict, which is at https://github.com/NVIDIA-developer-blog/code-samples/tree/master/MATLAB_deeplearning

I tried using the cnnPredict from the link But I am still getting this error

Reference to non-existent field 'dilate'.

Error in vl_simplenn (line 69)

'dilate', l.dilate, ...

Error in cnnPredict (line 26)

resTemp = vl_simplenn(cnnModel.net,

cnnPreprocess(predImage(:,:,:,1)), [], []);

Error in Untitled4 (line 22)

[~,scores] = cnnPredict(cnnModel, img,

'UseGPU',true,'display',false);

this happened previously when I tried removing the meta term as well the vl_simplenn error is whats bugging me now

Which packages did you load from where to put together this code? The ones I find on mathworks.com do not reference dilate, but I do see dilate documented for layers at https://www.vlfeat.org/matconvnet/mfiles/simplenn/vl_simplenn/
