  • Low bit-rate video coding using image triangulation and warping

    Publication Year: 1997, Page(s):161 - 164
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (500 KB)

    We proposed a new video coding method that results in a lower bit-rate than the MPEG-1 method. Instead of dividing the image frames into 8×8 blocks, the frames are triangulated according to a set of control points. The control points and the edges of the triangular blocks are located at the edge features in the image. These control points in the sequence are tracked and their motion is encod...

    Medium to high end colour TVs that are designed for an international market must operate over a wide mains voltage range, which typically images from 90 VAC to 276 VAC. To achieve operation over this wide mains voltage range, at the power levels that these sets require, a voltage doubler circuit is required at the front end. The doubler circuit consists of two electrolytic ca... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (400 KB)

    We propose to combine the min/max curvature to the surface diffusion model. The resulting technique is an automatic, extremely robust, computationally efficient, and a straightforward scheme. The flow under min/max curvature was presented by Malladi and Sethian (see Graphic. Models Image Processing, vol.58, no.2, p.127-141, 1996) in a differential equation in terms of the image intensity.

  • An improvement of bottom-up variable-sized block matching technique for video compression

    Publication Year: 1997, Page(s):157 - 160
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (388 KB)

    Block matching can reduce temporal redundancies. It is an important scheme in video compression. So far, there have been many methods proposed for this scheme, such as fixed-sized block matching (FSBM), top-down variable-sized block matching (TDVSBM), and bottom-up variable-sized block matching (BUVSBM). In these methods, the blocks in each frame of a video must be square, and that is why some obj... View full abstract»

    The Internet is the new infrastructure. It requires that we rethink the nature of devices. They no longer need be isolated. The cost of tapping into the global network is very low and the new capabilities are compelling. The designs need not be limited by what the device can do alone. We need to learn how to create such devices. What capabilities should be available locally and which can be shifte... View full abstract»
