Hi All,
thanx for assiting me in advance! i have some code i am understanding and needs some clarification on the pixel range and what it does!
can you help me understand this please!
here's the code!
pixelRange = [-30 30];
imageAugmenter = imageDataAugmenter( ...
'RandXReflection',true, ...
'RandXTranslation',pixelRange, ...
'RandYTranslation',pixelRange);
augimdsTrain = augmentedImageDatastore(inputSize(1:2),imdsTrain, ...
'DataAugmentation',imageAugmenter);

RandXTranslation and RandYTranslation are name-value pairs used to indicate the horizontal and vertical translations to be applied to the images for augmentation. For 2-element numeric vector inputs, the translation value is drawn from a uniform distribution specified by the range given in the name-value pair.
In this case the range is specified by the variable pixelRange.
Please refer to the following document link on imageDataAugmenter to get a better understanding about the augmentation procedure.
