A basic question at image sonification is the image segmentation. A cognitive model of visual processing in a greater degree could define possible ways of sound mapping. For instance, the scanpath theory suggests that a top-down internal cognitive model, of what we see, drives the sequences of rapid eye movements and fixations or glances that so efficiently travel over scene or picture of inter...

Extracting moving objects from a video shot provides a good low-level representation of videos. It provides object trajectory, color, shape characteristics. Combined with specific domain knowledge, it can be a powerful cue as what is going in a video shot. This paper proposes a unsupervised moving object extraction/tracking system that attempts to capture salient moving objects from an image se...

The paper presents a modification of a bottom up graph theoretic image segmentation algorithm to improve its performance. This algorithm uses Kruskal’s algorithm to build minimum spanning trees for segmentation that reflect global properties of the image: a predicate is defined for measuring the evidence of a boundary between two regions and the algorithm makes greedy decisions to produce the f...

Nowadays, the accumulation of paper in the life of business professional is overwhelming. Digital documents on the other hand being less expensive and more efficient are on the road to a more organized office. Also crucial for many business applications document image analysis is needed before OCR operation. Segmentation of document images into text and non-text regions is essential because OCR...
