Abstract :
This paper proved a new adaptive threshold in spherical coordinate system based on Besov space norm theory for application of the internet of things (IOT). It presented a new adaptive curve shrinkage function to overcome the limitation of translational functions. The new function could reach and exceed the true value and enhance the image edge. According to the image statistical characteristics in the spherical coordinates, to process the radial component with the new thresholds and new shrinkage function. The simulation experiments evaluated the new algorithm from the peak signal noise ratio, mean square error and running time.
