In a multiplexed sensor system, what is the term for the unwanted interference that occurs when unselected sensor lines influence the shared signal path due to capacitive or inductive coupling?

What is the main advantage of using hardware multiplexing in a sensor system with many sensing elements?

Using conformal tactile textiles*, it is possible to get a dense, wearable 2D map of pressure on the foot (pictured above - yellow = unloaded, blue = loaded). What two-dimensional DSP tool might you use to analyse these data and detect whether a person pronates or supinates?

Why have we chosen a Laplacian-of-Gaussians filter?

What is the accuracy at the sigma and threshold above (give as a percentage - XX%)

Which threshold should you use to maximise accuracy? (Answer format XX.XX) 

Process the images using a Laplacian-of-Gaussian. Which filter sigma (integer) gives you the best accuracy?

Applying a filter kernel to a 2D dataset in the space domain to perform operations like smoothing or edge detection is typically implemented using which mathematical operation?
