que about training images from cifar10data

I currently have a problem

I RUN THE CODE BUT IN THIS LINE THERE IS A PROBLEM:

Train an R-CNN object detector. This will take several minutes.

rcnn = trainRCNNObjectDetector(AcneAndBeautySpots, cifar10Net, options)

% rcnn = trainRCNNObjectDetector(trainingImages,cifar10Net , options, 'NegativeOverlapRange', [0 0.3], 'PositiveOverlapRange',[0.5 1])

I TRIED 2 KIND OF LINE BUT BOTH DONT WORK

THE ERROR IS:

>> thank you very match:)

Did you try following the suggestion,

Lower the first value of

PositiveOverlapRange to increase the number of positive region proposals.

[neora asulin]

yes

but it dont work

[neora asulin]

i tke table with 2 columns 1 for location images and secont the hight and width and max hight...(like a array with 4 numbers)

but it does not work still

Answer 1

[Sai Bhargav Avula]

Hi,

The error is because your region proposal method is producing ROIs that are too small to process. In the following link Birju gives a good explanantion.

Hope this helps !
