Abstract: The present invention relates to a method to divide spectrum sections to apply an interval threshold method even to XRF spectrum data with random properties by dividing the sections of the XRF spectrum using peak size characteristics, and to a method to analyze X-ray fluorescence using the same. The method to divide spectrum sections comprises: a step of reducing spectrum data through down sampling and then differentiating the reduced signal; a step of creating a cumulative graph by accumulating the differentiation results of the reduced signal; a step of detecting section division points using a gradient of the cumulative graph and the gradient rate; and a step of dividing the spectrum data into sections based on the section division points.

Abstract: PURPOSE: A preprocessing method for minimizing an abnormal value influence of spectrum data is provided to supply a result similar to an original signal by reducing an abnormal value found in a spectrum or other signals and performing preprocessing at a low calculation cost. CONSTITUTION: A difference value between a model and a target signal is obtained by selecting a model for the target signal. A noise and an abnormal value getting out of a predetermined range are removed by applying a median filter to the difference value. A preprocessed signal is restored by combining the processed signal with the model. A preprocessing result is obtained by applying smooth algorithm to the restored signal. [Reference numerals] (1) Obtaining a model of a target signal; (2) Applying a median filter to a difference between the model and the target signal; (3) Applying smooth algorithm by adding the filter applied value and the model

Abstract: PURPOSE: A method for generating and restoring value added copyright protection information for a still image is provided to prevent the quality from being degraded without the direct insertion of copyright information into the still image. CONSTITUTION: A method for generating and restoring value added copyright protection information for a still image comprises the following steps of: generating an arbitrary coordinate value and arbitrary pixel value within the size of the still image and the range of pixel values by generating random numbers; extracting a pixel value from the still image by using the arbitrary coordinate value; giving 1 when the extracted pixel value is identical or larger to or than the generated arbitrary pixel value; generating a binary image by giving 0 if the pixel value is smaller than the generated arbitrary pixel value; and generating value added copyright information by performing the EX-OR operation based on the binary image and separate copyright information.
