Wood Carving and Reliefs of Majuli: Its Importance and Contribution as an Art Form
Wood carving in various purposes and uniformly as an expression of art prevailed in every human society since the beginning of the Indus valley civilization or back to the centuries. It is closely attached to the different aspects of human life. A number of references can be traced in the civilization of Harappa that they used timbers to construct roofs of their abodes which were flat and made ...
متن کاملVideo Carving
We present a technique for summarizing a video into a short segment, while preserving the important events in the original. While many techniques remove whole frames from the video stream when condensing it, we observe that these deleted frames need not come from a single time step. More generally, deleted frames are “sheets” through the space-time volume. This leads to an algorithm whereby she...

Two African states, Tanzania and Zambia, are seeking to change the ban on trade in ivory at the meeting next month of the Convention on the International Trade in Endangered Species (Cites) in Qatar. But the countries face a battle, because other states, such as Kenya and Mali, are strongly opposed to any change and have been lobbying the EU in Brussels this month to support a block to any chan...
متن کاملShadow Carving
The shape of an object may be estimated by observing the shadows on its surface. We present a method that is robust with respect to a conservative classification of shadow regions. Assuming that a conservative estimate of the object shape is available, we analyze images of the object illuminated with known point light sources taken from known camera locations. We adjust our surface estimate usi...
متن کاملArc Carving
In this paper we present a new technique for improving the azimuth resolution of ultrasonic range sensors frequently used with mobile robots. This improvement is achieved without a significant increase in the latency, or processing delay, of the system. Our approach decreases the azimuth uncertainty of a sensor reading by eliminating portions of the reading that are contradicted by subsequent r...
