Earth Observation Software System for Fire Monitoring

A software system is developed for the purposes of fire detection and monitoring based on satellite data acquired by remote sensing of the Earth. The MODIS sensors on board of satellites Terra and Aqua are utilized. Fire detection is based on a contextual algorithm. After processing the data the det...

Efficient compression of multispectral and multi-view images

The new approach is based on the Inverse Pyramid Decomposition (IPD). The IPD was investigated by Prof. Kountchev (European patent) and on the basis of this invention was developed application software (C++, Windows environment). The idea is based on the human way for object analysis and recognition...

Image compression, Documents content protection; Digital watermarking; Hierarchical access in databases.

Detection of welding defects in X-ray images and photos

The offered R&D Result is reliable and flexible. It extracts welding defects with high accuracy, which is a reliable basis for the extraction of features, representing the geometry or brightness qualities (contrast, position, aspect ratio, width-area ratio, length-area ratio, and roundness), togethe...

Nondestructive analysis; welding defects detection; detection of heli-arc defects.

Software tools for adding sign language information for hearing impaired people

The R&D result aimed the creation of efficient software tools for presenting educational information for hearing impaired people in their natural language – the sign language. The new approach is to add sign language representations to existing regular training courses, which is available on request...

Sign language interpretation, Contours extraction, Lossless image compression, coding of video sequences.

Archiving and content protection of electronic documents

The new approach is based on the Inverse Pyramid Decomposition (IPD) with insertion of multiple watermarks. The IPD was investigated by Prof. Kountchev (European patent) and on the basis of this invention was developed application software (C++, Windows environment). In result of the decomposition, ...
