Abstract   In this paper, we propose a new method for kernel based object tracking which tracks the complete non rigid object. Definition the union image blob and mapping it to a new representation which we named as potential pixels matrix are the main part of tracking algorithm. The union image blob is constructed by expanding the previous object region based on the histogram feature. The pote...

During the last decade, performance improvements in top sports have been increasingly driven by technological innovations. This paper discusses the application of video analysis for training registration in swimming. In current practice, coaches have limited means to evaluate objectively and quantitatively how a training session was carried out. We propose the use of a video-based registration ...

Context. User Interfaces (UIs) intensively rely on event-driven programming: widgets send UI events, which capture users’ interactions, to dedicated objects called controllers. Controllers use several UI listeners that handle these events to produce UI commands. Objective. The first objective of this work is to show empirical evidences that the code that describes and controls UIs can be affect...

A method for the monitoring of anomalous human behaviour that is based on the logical description of complex human behaviour patterns and special kinds of blob (a separated area of a foreground image) motion statistical metrics is developed. The concurrent object-oriented logic language is used for the analysis of graphs of tracks of moving blobs; the graphs are supplied by low-level analysis a...

We describe a multi-loop robotic control architecture that for the fine-motion control required for object tracking uses two different loops that depend on entirely different approaches for visual servoing. One tracking loop uses fast blob analysis of the camera images for servo control. The other tracking loop, which is more robust but slower, uses model-based line matchings for a more robust ...

Two-dimensional gas chromatography (GC×GC) plays a central role into the elucidation of complex samples. The automation of the identification of peak areas is of prime interest to obtain a fast and repeatable analysis of chromatograms. To determine the concentration of compounds or pseudo-compounds, templates of blobs are defined and superimposed on a reference chromatogram. The templates then ...

One month’s worth of POLAR UVI data were subjected to a ‘‘blob’’ analysis to determine the statistical dynamics of substorm features observed in the LBHL band (152-188 nm). Adapted from similar DoD analyses of target images, the analysis consists of finding, on a frame-by-frame basis beginning at substorm onset, the following aspects of an individual auroral feature: peak power (i.e., power of ...

MOTIVATION New generation Affymetrix oligonucleotide microarrays often have blob-like image defects that will require investigators to either repeat their hybridization assays or analyze their data with the defects left in place. We investigated the effect of analyzing a spike-in experiment on Affymetrix ENCODE tiling arrays in the presence of simulated blobs covering between 1 and 9% of the ar...
