The present invention relates to a classification apparatus for pathologic diagnosis of a medical image and a pathologic diagnosis system using the same. According to the present invention, there is provided a classification apparatus for pathologic diagnosis of a medical image, including: a feature extraction unit configured to extract feature data for an input image using a feature extraction variable; a feature vector transformation unit configured to transform the extracted feature data into a feature vector using a vector transform variable; and a vector classification unit configured to classify the feature vector using a classification variable, and to output the results of the classification of pathologic diagnosis for the input image; wherein the feature extraction unit, the feature vector transformation unit and the vector classification unit are trained based on a first tagged image, a second tagged image, and an image having no tag information.

Provided are an asymmetric butadiene-based charge transporting compound represented by one of Formula (1) and (1') as in claim, an electrophotographic photoreceptor including the asymmetric butadiene-based charge transporting compound, and an electrophotographic imaging apparatus. The electrophotographic photoreceptor including the organic photoconductive material as a charge transporting material may not cause a problem, such as partial crystallization during film formation and may have a high charge potential, a sufficient photoresponsive property with high sensitivity, and a high durability. Moreover, these properties may be all maintained even in the case of exposure to light as well as use in low-temperature environments or high-speed processes, thus having high reliability.
