Abstract: With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a ne...

For the first time, a complete wireless and mobile emergency TeleOrthoPaedics system with field trials and expert opinion is presented. The system enables doctors in a remote area to obtain a second opinion from doctors in the hospital using secured wireless telecommunication networks. Doctors can exchange securely medical images and video as well as other important data, and thus perform remot...

This paper presents an error concealment technique for image transmission in JPEG2000 for the lowest frequency coefficients. The proposed method uses the layer structure that is a feature of the JPEG2000. The most significant layer is hidden in place of the lowest layer of the bit stream. After transmission this embedded layer is used for error concealment. The bit stream encoded using the prop...

The growth of manufacturing was central to the economic development of nineteenth century America. In the early stages of industrialization, the commitment to produce was frequently seasonal or part-time, and establishments might shut down operations for weeks or months at a time. But, as transportation improved and markets widened in their geographic scope and, as technological and organizatio...

A new species of the ichneumonid subfamily Labeninae, Apechoneura seminigrasp. n., is described. Specimens were collected from the Amazon Rainforest of Colombia.

The fractal image compression technique models a natural image using a contractive mapping called fractal mapping in the image space. In this paper, we demonstrate that the fractal image coding algorithm is compatible with other image coding methods. In other words, we can encode only part of the image using fractal technique and model the remaining part using other algorithms. According to suc...

New devices gaining access to the Internet need to obtain multimedia content adapted to their limited capacities. Scalable formats allow to retrieve different versions of a single file by simple manipulations of the bitstream. However, prior knowledge of the data structure is required to perform these operations. In this paper, XML is used to describe the structure of a bitstream. The resulting...
