Provided are an image system and an image reconstruction method using the same. The image system includes an image scan device, a spectrum signal generation device, and an image recovery device. The image scan device generates a magnetic particle detection signal on the basis of an induced magnetic field induced from a magnetic particle. The spectrum signal generation device transforms the magnetic particle detection signal to a detection spectrum signal on the basis of a two-dimensional Fourier transform kernel. The image recovery device generates an image signal on the basis of the detection spectrum signal and a system matrix. According to the inventive concept, a data amount for image reconstruction may be ensured.

Provided is a method and apparatus for classifying geological materials using image processing techniques. The method and apparatus classify geological materials including stones, rock samples, and rock surfaces according to type and state by sequentially applying image processing techniques, such as a color space analysis, a granulometry analysis, texture parameter extraction and texture statistics extraction, to digital images of the geological materials. Since the method and apparatus extract quantitative figures that represent an entire image region by applying various image processing techniques, such as the color space analysis, the granulometry, the texture parameter extraction and the texture statistics extraction, to the digital images of the geological materials, the geological materials can be classified, which is not possible using a conventional image processing technique.
