Multifocus image fusion generates a single image by combining redundant and complementary information of multiple images coming from the same scene. The combination includes more information of the scene than any of the individual source images. In this paper, a novel multifocus image fusion method based on extreme learning machine (ELM) and human visual system is proposed. Three visual features that...
In the traditional image mosaic algorithm based on seam line, the line is searched by making the color and neighborhood structure difference as small as possible in the overlap region of the images. However, when a small object with single color and symmetrical structure appears, the color and the neighborhood structure difference are not able to restrain the direction of the seam line. The appearance...
Multimodal medical image fusion plays a vital role in different clinical imaging sensor applications. This paper presents a novel multimodal medical image fusion method that adopts a multiscale geometric analysis of the nonsubsampled contourlet transform (NSCT) with type-2 fuzzy logic techniques. First, the NSCT was performed on preregistered source images to obtain their high- and low-frequency subbands...
Operating excavator on the risk surroundings is not safe for human to control on site. Consequently, automatic excavator called Field Robot has been researched to protect the workers from the hazardous environments. The remote excavation system is required to perform in such environments. This paper presents the study on remote control system for the Field Robot and augmented reality vision for user...
A novel learning based automatic method is proposed to detect the fetal head for the measurement of head circumference from ultrasound images. We first exploit the AdaBoost learning method to train the classifier on Haar-like features and then, for the first time, we propose to use prior knowledge and online imaging parameters to guide the sliding window based head detection from ultrasound images...
The paper presents a relative novel time-frequency analysis method which applies in the vibration Fault analysis of rotor systems through Hilbert spectral analysis (HSA), the part of the Hilbert-Huang transform. Using this method we analyze the vibration fault characteristics of the rotor system with rub-impact by compared with non-rubbing rotor system both in experiment and simulation. Firstly, a...
A Method, to locate eye in image by using gray projection, is presented. We utilize the gray differential projection cure of the facial image to locate eye vertically position and utilize the gray integral projection cure to locate eye horizontal position. The method can apply to not only the upright front side face, but also the upright side face, lift up face and low face. When the face in image...
In the near future along with the advent of WIMAX, 3GPP has also started a long-term evolution of UMTS technology project. Presently, the basic channel transmission technology of uplink and downlink has been determined, up-SC (single carrier)-FDMA, downlink using orthogonal frequency division multiplexing technology. Characteristic specifically for the wireless decaying channel, a new channel estimation...
