Image Preprocessing Faster Than Ever

Ideal for Large Images or High-speed Applications

A new HALCON interface from MVTec, makes it possible to directly run filter operations on the microEnable III frame grabber from Silicon Software, making image processing applications with HALCON dramatically accelerated.

VisualApplets Studio by Silicon Software enables MVTec customers to directly execute computationally expensive image preprocessing on the frame grabber in an easy way. Thus, with the new HALCON interface, more computing power remains for the following high-level image processing with HALCON.

By image preprocessing on the frame grabber's FPGA (field programmable gate array), significant computing time can be saved on the main processor. Based on a graphical user interface, the preprocessing can be flexibly configured such as a media filter operation for noise reduction. The user does not need any expertise in FPGA programming and can select which algorithms are preprocessed by the FPGA and which remain for the subsequent application.

This proceeding especially is of interest whenever huge amounts of data have to be processed. This concerns mainly high-speed applications or applications dealing with large images, e.g., images acquired from line scan cameras.
