The form and content of the white blood cells are the important manifestations of human body health indicators. In color blood cell images, segmentation and recognition are two essential issues in the automatic white blood cells (WBC) identification system. Since WBC can be approximately regarded as elliptic shape, so using the ellipse detection method can successfully recognize such elements. Whether...
This paper addresses the problem of simultaneously estimation of 3D structure and motion of moving surfaces from multi-view sequences. We model the surface locally as a 9-parameter spatio-temporal plane and a region growing mechanism is used to guarantee proper initial values are provided for parameter estimation. The algorithm starts with feature points that have been matched across views and time,...
We report on a droplet-based, in situ formed tunable cylindrical microlens array in microchannels. The deionized water microlenses are formed via liquid-air interfaces of liquid droplets at T-shaped junctions of octadecyltrichlorosilane (OTS) treated polymerized isobornyl acrylate [poly(IBA)] microchannels, and their focal length can be tuned individually by pneumatic manipulation. These microlenses...
This paper aims to locate a tag position inside the building by using low cost device with minimal location error. The enhancement approach with received signal strength indication (RSSI) technique is proposed to achieve the target. In this paper, after introducing the existing LANDMARC system, we try to construct the relationship between RSSI and distance from reader to tag by experiment. Finally,...
