The Conversion Method From Image to Complex Number and Its Application in Image Secret Sharing
图像的复数表示及其在图像秘密分存中的应用

Concerning the image expression and operation problem of traditional image processing, the novel idea that expressing an image in complex plane is proposed. The conversion method of mapping image to complex number is presented, and the operations of addition, subtraction, multiplication and complex conjugate of image are defined in a new point of veiw. Hence, Combined with the existing threshold access structures scheme, it leads to proposal of using complex number based secret sharing schemes in color images sharing. Experimental results validated that it effectively solved the problems of the size of the shares and the number of colors,etc.
