Biological cells segmentation

Biological cells segmentation

Biological cells segmentation     Cell segmentation is very important task in medical image processing. The aim of the project was to develop the automatic solution for specific biological cells segmentation. We shouldn’t talk about biological details of the challenge as this is not our research field and just focus on computer vision algorithms. Our objective in this area was to develop robust and precise algorithm for automatic structural segmentation

High-performance autofocusing for Synthetic Aperture Radars

High-performance autofocusing for Synthetic Aperture Radars

High-performance autofocusing for Synthetic Aperture Radars     Synthetic aperture radar (SAR) systems are very popular instrument for high-resolution image of ground surface. Unlike to optical systems, SAR can be used in all weather and lighting conditions. A basic idea of SAR technique is coherent processing of received signals on a moving platform (aircraft or satellite). The main challenge is to perform very precise measurements of platform position at each

Robust Number Plate Detector

Robust Number Plate Detector

Robust Number Plate Detector     The goal was to develop the approach for the automatic detection of the number plate area from the vehicle image. A typical ANPR algorithm includes several steps (Fig. 1): The number plate detection is a crucial step since it strongly affects on the overall system performance. For this purpose utilized the following Stroke width transform (SWT) Blob detection algorithm The SWT (https://app.box.com/s/cvejwymu1jq0ii1rec12j824rksotr7k) is a well-known text detection algorithm. Its

Road detection algorithm     Our task was to develop the algorithm for the automatic road detection in radar images. The challenge was that the radar images are a bit different from the optical ones. In particular, in the case of synthetic aperture radar (SAR), the image formation process is accomplished via coherent processing of the received signals backscattered from the Earth surface. As a result, the multiplicative speckle noise appears in the SAR images. It complicates

People tracker     Systems for detection and tracking of moving objects have a high demand nowadays. Our purpose was to develop the system for the analysis of the humans’ activity in the supermarket. In particular, to cluster the regions of interest (ROI), to detect, track and count the people​. Below is the basic scheme of the “People Tracker” framework: Fig. 1.
