It interprets image editing as a variational problem concerning the adaptive adjustments to the zero- and first-derivatives of the images which correspond to the color and gradient items. By varying the definition domain of each of the two items as well as applying diverse operators, the new model is capable of tackling a variety of image editing tasks. It achieves visually better seamless image cloning effects than existing approaches. It also induces a new and efficient solution to adjusting the color of an image interactively and locally. Other image editing tasks such as stylized processing, local illumination enhancement and image sharpening, can be accomplished within the unified variational framework. Experimental results verify the high flexibility and efficiency of the proposed model.展开更多
文摘The characteristics and functions of academic journals and the new demand for documentary information in academic journals in the information age are expounded.By introducing the characteristics of edition and dissemination of printed journals,secondary documents and academic journals(CD),the paper emphasizes the importance of large scale integration and secondary edition of documentary information in journals for enhancing information dissemination and availability ratio of academic journals.
