In this paper, we propose a novel scheme of Local Histogram Equalization (LHE) using guided image filter. The sub-blocks are segmented from the input image, after which we individually compute each local histogram used for multiple transformation functions. To further remove the block artifacts caused by LHE, we employ the input image to guide the texture information, while keeping the enhancement...
Consumer Electronics has long been about connected things going back to the days of radio and television and to component Hi-Fi systems. The Internet and, more to the point, the Internet of Things represents a fundamental shift from creating value in hardware to creating value using software. This fundamental shift challenges industries and public policies. Value is created outside of networks using...
IR LEDs are widely employed in the Internet protocol cameras to increase the imaging effects on the very dark scenes. Hence, the production yield of IR LEDs significantly affects the performance of displaying effects for IP cameras. In this paper, we propose a very efficient way to estimate the IR LED production yield based on image processing technique. Experimental results show that our method effectively...
Tilt-Shift photography captures specific focused range by tilt-shift lens. The tilt-shift lens compensate the perspective problems by tilt and change the depth of field by shift. Using the tilt-shift lens, the viewers can pay their attention to the specific objects naturally. In this paper, we develop an automatic method to produce tilt-shift images. An energy minimization approach is proposed by...
This paper presents an application on mobile phones that translates Chinese menus into a 3D model of the menu and the name of the menu in English. The system runs on an android platform mobile phone. It uses image recognition to trace and register image markers (in this paper it is a Chinese word). Then, it processed the input into a pre-processed feature database of menu items using Features from...
This paper presents a technique that generates rough depth maps from laparoscopy camera using feature tracking techniques for depth sampling. The method is applicable to single laparoscopy video images through local motion cues to improve the inferred depth maps. The feature tracking is used to ensure temporal depth consistency, such as SURF. The results show that the proposed methods significantly...
In this work, we propose a fragmentation resilient IP identification based data embedding method. First, we analyze the IP identification generation in various operating systems to validate the feasibility of our proposal. Then, we put forward our proposal to embed data into IP identification field while considering data from the payload field. Results suggest that the proposed method resembles the...
Digital image forgery is becoming easier to perform because of the rapid developments of various manipulation tools. Between the various image forgery techniques, image splicing is considered as one the most prevalent technique. In this paper, a low dimensional singular value decomposition (SVD) based feature extraction method applied in steganalysis is proposed as an image splicing detection method...
