The flexible pinhole camera (FPC) allows flexible modulation of the sampling rate over the field of view. The FPC is defined by a viewpoint and a map specifying the sampling locations on the image plane. The map is constructed from known regions of interest with interactive and automatic approaches. The FPC provides inexpensive 3D projection that allows rendering complex datasets quickly, in feed-forward...
For homogeneous transcoding, we usually transfer a compressed video into a lower bit-rate and/or video with a smaller size. In this paper we introduce the general architecture of a downing sizing transcoder and propose some novel techniques for its practical realization, including motion vector re-estimation, sub-pixel motion re-estimation, mode re-decision, etc. We then generalize the idea of transcoding...
PMMA-based MOF with 547 air holes was fabricated by extruding and stretching of an big-size preform with hole diameter of 1.5 mm and hole spacing of 1.9 mm. The high image resolution was demonstrated.
The subject investigated in this paper is oil-water two-phase flow, an image data capture system (IDCS) for 8 electrodes electrical capacitance tomography (ECT) of oil/water two-phase flow is discussed, an alternating current circuit measuring small capacitance and a control circuit of data capture are designed. The advantages of the system are as followings: the high measuring speed, the high-resolution...
