Corvie.AI – Laplacian filter in EEG singal processing Neuroscience
The Laplace filter removes the low-frequency component and enhances the high-frequency structure of the signal. The strong low-frequency component arises from the intersection of the scalp/skull.
❌ Disadvantages:
- Deep sources are lost
- Based on sensors, not on data -> IDEA 💡: make an algorithm that imply the "knowledge" of the sensors location, or the scalp manifold influence from the different sources. Can be simulated first -> get approximation -> apply with the filtering. Ideas/EegDeepLaplacian
