| 20120014586 | Method for Brightness Level Calculation in the Area of Interest of the Digital X-Ray Image for Medical Applications - The invention relates to methods for evaluation a level of brightness in the area of interest of the digital x-ray image for medical applications by means of the image histogram using a neural network. The calculations comprise of: image acquisition, image histogram calculation, converting histogram values into input arguments of the neural network and output values of the neural network acquiring. As input arguments of the neural network the histogram values calculated with the given class interval and normalized to unit are used. The level of brightness is calculated as a linear function of the output value of the neural network. Neural network learning is performed using a learning set calculated on the base of the given image database; as a set of target values the levels of brightness calculated for each image over the area of interest and scaled to the range of the activation function of a neuron in the output layer of the neural network are used. | 01-19-2012 |
| 20120008849 | Method for Correction of Digital Images - The method for correction of a digital image acquired with the use of electromagnetic radiation including X-rays, converted into electric signal and sent to digital imaging device, is provided, comprising pyramidal decomposition of a digital image into detailed and approximation images, removal of scattered radiation in approximation part of the images, contrast enhancement in detailed part of the images, merging of processed detailed and approximation images, the following reconstruction and generation of the final image. The results of the embodiment of this method comprise removal (reduction) of the scattered radiation component, noise reduction, correction of the dynamic range of the output image in accordance with the dynamic range of the output device, and scaling of the dynamic range of the output image in accordance with the dynamic range of the original image. | 01-12-2012 |
