Now, although I do very much like this statement in itself, I do not think that all functions are already covered. So my question of interest: Is Scilab planning an update with more functions?

However, things changes and currently I am working more on Machine learning fields (deep learning), and yes, I am still using IPCV for POC of certain algorithms for the team members to deploy, using IPCV for inferencing with the models built, and also Scilab web tools to sent images to the API for deployment test. Due to the current workload, I might not be able to further develop the module, at least for near future, but anyone would like to continue to further develop the module, please feel free to do so from : https://github.com/tanchinluh/IPCV If any university would like to take up the project, I would be more than happy to give a few hours of free training to students on how to add functions into the module, provided the university is keen to take up the responsibility and put commitment on the development. You could reach me here.
