The manual counting of cell colonies, or viral plaques is a laborious, inaccurate task. The work here investigates a low-cost alternative to professional colony / plaque counters. We used an off the shelf webcam, and image processing software (MATLAB) in conjunction with well studied image processing techniques, primarily the watershed transform and the regional maxima transform. With these met...

An approach for Electroencephalogram (EEG) processing is presented. Along with the theoretical development of stochastic processing techniques, two application areas are suggested: EEG sleep recording analysis and Brain Computer Interface (BCI). Many methods have been already developed in the area of sleep staging, nevertheless the automatic scoring in not still so effective as the manual scori...

Online social media has been recognized as a valuable information source for disaster management whose volume, velocity and variety exceed manual processing capacity. Current machine learning systems that support the processing of such data generally follow a human-in-the-loop approach, which has several inherent limitations. This work applies the human-is-the-loop concept from visual analytics...

Historically, story understanding systems have depended on a great deal of hand-crafted knowledge. Natural language understanding systems that use conceptual knowledge structures [Schank and Abelson, 1977; Cullingford, 1978; Wilensky, 1978; Carbonell, 1979; Lehnert, 1981; Kolodner, 1983] typically rely on enormous amounts of manual knowledge engineering. While much of the work on conceptual kno...

Videobased sign language recognition is barely investigated in the field of image processing. General conditions like realtime-ability and userand environmentindependence require compromise solutions. This paper presents a system for automatic analyzing of the facial actions. For this point distribution models and active shape models are brought into action. Additional a comparison is made betw...

This paper introduces a device, algorithm and graphical user interface to obtain anthropometric measurements of foot. Presented device facilitates obtaining scale of image and image processing by taking one image from side foot and underfoot simultaneously. Introduced image processing algorithm minimizes a noise criterion, which is suitable for object detection in single object images and outpe...

Balancing (equalization) of latency in parallel paths in the pipelined data processing system is an important problem. Without that the data from different paths arrive at the processing blocks in different time cycles, and incorrect results are produced. Manual correction of latencies is a tedious and error-prone work. This paper presents an automatic method of latency equalization in systems ...

Manual processing of a large volume video data captured through closed-circuit television is challenging due to various reasons. First, manual analysis highly time-consuming. Moreover, as surveillance videos are recorded in dynamic conditions such the presence camera motion, varying illumination, or occlusion, conventional supervised learning may not work always. Thus, computer vision-based aut...

Image processing algorithms for individual corn plant and plant stem center identification were developed. These algorithms were applied to mosaicked crop row image for automatically measuring corn plant spacing at early growth stages. These algorithms utilized multiple sources of information for corn plant detection and plant center location estimation including plant color, plant morphologica...

Two assembly line balancing problems are addressed. The first problem (called SALBP-1) is to minimize number of linearly ordered stations for processing n partially ordered operations V = {1, 2, ..., n} within the fixed cycle time c. The second problem (called SALBP-2) is to minimize cycle time for processing partially ordered operations V on the fixed set of m linearly ordered stations. The pr...
