Segmentation of handwritten text into individual characters is an important step in many handwriting recognition tasks. In this paper, we present two segmentation algorithms based on elastic shape analysis of parameterized, planar curves. The shape analysis methodology provides matching, comparison and averaging of handwritten curves in a unified framework, which are very useful tools for designing...
A major insight from our previous work on extensive comparison of super pixel segmentation algorithms is the existence of several trade-offs for such algorithms. The most intuitive is the trade-off between segmentation quality and runtime. However, there exist many more between these two and a multitude of other performance measures. In this work, we present two new super pixel segmentation algorithms,...
Identifying intermediate biomarkers of Alzheimer's disease (AD) is of great importance for diagnosis and prognosis of the disease. In this study, we develop a new AD staging method to classify patients into Normal Controls (NC), Mild Cognitive Impairment (MCI), and AD groups. Our solution employs a novel metric learning technique that improves classification rates through the guidance of some weak...
Delaying the analysis launch until the completion of the handwritten word scribing, restricts on-line recognition systems to meet the highly responsiveness demands expected from such applications, and prevents implementing advanced features of input typing such as automatic word completion and real-time automatic spelling. This paper proposes an efficient Arabic handwritten characters recognizer aimed...
Perceptual quality evaluation of the retargeting image plays an important role in benchmarking different retargeting methods, as well as guiding or optimizing the retargeting process. The distortions introduced during the retargeting process are mainly categorized into shape distortion and content information loss [1]. The shape distortion measurement is critical to the evaluation of retargeting image...
A demonstration is made of the high-speed real-time image processing capabilities of the SCAMP-5 vision chip. The device provides a software-programmable 256×256 pixel-parallel SIMD processor array. In the example application, the IC can determine dimensions and the location of a single object, at a sustained rate of 100,000fps. At 30,000fps, the chip can return the same metrics from 5 objects. This...
One form of molecular communications for short range transmission between nanomachines is Calcium Signaling. This form of signaling is commonly found in cellular tissues, which consist of tightly packed cells, whereby Ca2+ ions propagate and diffuse between the cells. However, the natural flexible structure of cells usually leads to them dynamically changing shapes under certain strains and forces...
Defocus blur is an indicator for the depth structure of a scene. However, given a single input image from a conventional camera one cannot distinguish between blurred objects lying in front or behind the focal plane, as they may be subject to exactly the same amount of blur. In this paper we address this limitation by exploiting coded apertures. Previous work in this area focuses on setups where the...
Alignment of module connectors is a crucial component of self-reconfiguration in modular robotics. Accomplishing this process using passive mechanical geometry saves resources such as space and power for the modular robot. We present concepts for evaluation of these geometries as well as a new 3D geometry, the 3D X-Face. For comparing different connectors independent of the rest of the robot, figures...
Circular dependencies between software artefacts are widely considered as problematic. However, empirical studies of Java programs have shown that most programs are riddled with circular dependencies. This seems to imply that not all circular dependencies are as detrimental to software quality as previously thought. Clearly, a better understanding of the types of circular dependency and their effect...
This paper presents a Document Image Analysis (DIA) system able to extract homogeneous typed and handwritten text regions from complex layout documents of various types. The method is based on two connected component classification stages that successively discriminate text/non text and typed/handwritten shapes, followed by an original block segmentation method based on white rectangles detection...
The majority of current research on sensor network localization focuses on wireless sensor networks deployed on two dimensional (2D) plane or in three dimensional (3D) space, very few on 3D surface. However, many real world applications require large-scale sensor networks deployed on the surface of a complex 3D terrain. Compared with planar and 3D network localizations, surface network localization...
Cell detection plays a significant role in automated biomedical image analysis. However, it is challenging to achieve accurate detection due to dense crowding/touching of cells. In this paper, we propose a robust decomposition algorithm for cell detection on adipocyte images. It formulates the decomposition into a cut selection problem using the polygon triangulation approximation and a specific-defined...
The analysis of the morphological differences between normal and pathological neuronal structures is of paramount importance. Some methods for the comparison of axonal trees only take into account topological information (such as TED), while others also include geometrical information (such as Path2Path). In a previous work, we have presented a new method for comparing tree-like shapes based on the...
Execution profiles form the basis of many dynamic program analysis techniques developed to solve problems in fields such as software testing, fault localization, and program comprehension. A typical profile comprises information that approximates the execution path of a program, specifically, the frequency of occurrence of program elements that are structural in nature, such as statements, branches,...
User experience design is crucial to achieve a successful intelligent product design. By taking the user experience design of a xylophone playing robot as an example, this paper attempts to identify the prominent attributes in the user experience design of intelligent products, and to find the general norms guiding the design. Both the pragmatic and the hedonic aspects have been investigated via questionnaires...
Red Blood Corpuscles are one of the most vital cellular components of human circulatory system. In normal physiological condition, an RBC is circular in front view and biconcave in side view. Also it is 7.5 Itm in diameter and 2 μm in thickness in terms of size. The normal morphology of an RBC undergoes some specific changes due to the consequence of different pathological abnormalities. One of such...
The development of new hardware implementations for stereo vision algorithms requires to establish a balanced trade-off among accuracy, speed and resource consumption requirements. FPGA-based devices allow devising flexible implementations fitting specific applications demands. In this paper, we propose a low resource FPGA-based solution for the calculation of the disparity map in a stereo vision...
Despite many years of research, comparing multiple protein structures simultaneously (multiple structure comparison) is still a challenging problem. Most of the previous studies have focused on similarities among subsets of residues (or atoms) from a group of proteins (local structure alignment) by minimizing some similarity scores based on root mean square deviation (RMSD) of the aligned residues...
This paper deals with person re-identification in a multi-camera scenario with non-overlapping fields of view. Signature based matching has been the dominant choice for state-of-the-art person re-identification across multiple non-overlapping cameras. In contrast we propose a novel approach that exploits pairwise dissimilarities between feature vectors to perform the re-identification in a supervised...
