The manner which calculates the luminosity level in the object domain of the digital x-ray image of medical application

摘要

It regards the manner which evaluates the level of the luminosity where this invention depends on the image histogram which uses neural network, in the object domain of the digital x-ray image of medical application. Calculation has, with the output value of the neural network which it converts and acquires and to the entry argument of neural network of image acquisition and image histogram calculation and histogram value. It is calculated as an entry argument of neural network, by the class width of given, it can use the histogram value which is normalized in the unit. Level of luminosity is calculated as linear function of output value of neural network. Neural network study, is done making use of the study set which was calculated on the basis of the image-database of given. It was calculated concerning object domain each image of the whole, scaling it was done vis-a-vis the range of activated function of the neuron in the output formation of neural network, it can use the level of luminosity, as set of set point.
