Re: March 20 - Day THREE: Improving Image Understanding by Improving Image Quality

@Michael, whats a good kernel size for the ISP pipeline, does the size stay the same for every ISP block? for example 3x3, 5x5, 8x8 ?

That's a complicated question, and it depends on the algorithm, the sensor resolution and the optics. For example, a good Bayer demosaic needs at least 7x7, a sharpening kernel probably 3x3 or 5x5, a spatial NR kernel could be much bigger --our biggest is 128x64! It depends on the characteristic scale of the feature being processed. Obviously with high megapixel sensors, a given feature requires bigger kernels.

The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
