AI teams are increasingly turning to synthetic data to meet their needs when real data is thin, or when handling sensitive information as the dataset wont contain any real information during the model training process. Thus, it is often recommended to collect diverse real-world data for training (and use active learning techniques to curate more efficiently), rather than relying on synthetic data. Synthetic data can also simulate edge cases and conditions that arent represented in real data or mitigate issues caused by potential changes in the camera sensor or lighting conditions, helping teams fill in the gaps in their dataset. Plotting the segmentation masks has never been so exciting! Afterwards, you can easily overlay the segmentation by doing: Changing the alpha will change the opacity of the overlay. Here are the RGB triplets for the default colors that MATLAB uses in many types of plots. For a point of comparison, employing image segmentation is particularly useful when dealing with use cases in a model where you need to definitively know whether or not an image contains the object of interest and also what isnt an object of interest.
