Innovative Methods for Digital Image Processing
Classic systems Classic solutions for digital image processing have always been closely tied to their producer. The maintenance and evolution of such a system depended on its
producer and could not be taken care of by a third party. Such a system is inadequate, and involves high costs for proprietary hardware and software.
Nowadays the rapidly rising number of applications for image processing and their continuous integration into production processes lead to the need for interoperable systems which are
compatible with standard interfaces. Our MontiVision Development Kit strives to achieve such interoperability in a cost effective fashion.
Digital Image Processing Under Windows 2000/XP
Under Microsoft Windows the DirectX API has allowed for quick processing of image data for some time now. DirectX offers the advantage of providing an API that will work on any computer,
no matter what hardware. DirectX takes advantage of the performance available in modern graphic adapters, and passes this on to the developer. By using DirectX, applications automatically
benefit from new features supplied by new hardware, without making any modifications to there old applications. DirectX ensures maximum compatibility, for the present and future.
DirectX In order to make this performance accessible for video processing, Microsoft developed the DirectShow API which is part of DirectX. DirectShow opens the possibility of
component based software development using the COM standards. These components can be connected and direct the video stream through each linked component (DirectShow filters).
Video data can be obtained through any framegrabber that has a VfW (Video for Windows) or WDM (Windows Driver Model) driver. This means that the software is not tied down to any
framegrabber, and can be changed at any time. The rendering of the picture on the monitor is handled by the video renderer, a DirectShow component which takes advantage of the high
performance graphic capabilities of the video card.
Between the capture filter and the renderer filter any number of transformation filters can be linked to manipulate and process the video stream. The control of each component and the data
stream in general is performed by a main application which can connect, disconnect, start or stop each and every component as the necessity arises. The MontiVision Development Kit offers a
comprehensive development environment for digital image processing based on DirectX.
To see how the MontiVision Development Kit simplifies the process, have a look at some of the example applications created by MontiVision.
Advantages
