helperSanitizeBoxes is a function provided in some object detection examples but is not a built-in function?

I've been working with the object detectors and some of the supporting functions call "helperSanitizeBoxes" which I assume helps with bounding boxes overextending the image dimensions. I've tried looking up this function, but am curious if anyone has insight into what it does/how it can be released.

sir, please check the default example folder，such as

C:\Users\Administrator\Documents\MATLAB\Examples\R2021a\deeplearning_shared\DeepLearningFasterRCNNObjectDetectionExample

may I upload helperSanitizeBoxes.m just for discussion

Thank U @yanqi liu..It Works. I was facing the same problem. Plz continue helping.

Hi,

The function helperSanitizeBoxes is used to clean up invalid bounding box data. Boxes with values <=0 are removed and fractional values are rounded to integers. If none of the boxes are valid, this function passes the data through to enable downstream processing to issue proper errors.

For more information about this function you can run the following example where you can open the helperSanitizeBoxes.m file available in current folder section:

where is this function, I cannot find it in any of deep learning tutorial? also at the end of this tutorial there are only two functions i.e. augment and preprocess data... and no sanitizebox

Run the example in MATLAB Online or MATLAB Desktop. This is where it will appear in MATLAB online:

It does not appear for me, I'm using matlab R2020b. It doesn't download with the example code.
