Image segmentation is one of the most common steps in digital image processing. The area many image segmentation algorithms (e.g., thresholding, edge detection, and region growing) employed for classifying a digital image into different segments. In this connection, finding a suitable algorithm for medical image segmentation is a challenging task due to mainly the noise, low contrast, and steep...
The massive amount of fine-grained parallelism exposed by a GPU program makes it difficult to exploit shared cache benefits even there is good program locality. The non deterministic feature of thread execution in the bulk synchronize parallel (BSP) model makes the situation even worse. Most prior work in exploiting GPU cache sharing focuses on regular applications that have linear memory acces...
With increasing interest in sophisticated graphics capabilities in mobile systems, energy consumption of graphics hardware is becoming a major design concern in addition to the traditional performance enhancement criteria. Among the different steps in the graphics processing pipeline, we have observed that memory accesses during texture mapping – a highly memory intensive phase – contribute 30-...
Due to their importance for studies oi wireless networks, recent years have seen a surge of activity on the design of local algorithms for the solution of a variety of network tasks. We study the behaviour of algorithms with very low localities. Despite of this restriction we propose local constant ratio approximation algorithms for solving minimum dominating and connected dominating set, maxim...
Cache performance in modern computers is important for program efficiency. A cache is thrashing if a significant amount of time is spent moving data between the memory and the cache. This paper presents two cache thrashing examples, one in scientific computing and one in image processing, both of which involve several one-dimensional arrays that are accessed sequentially, i.e., with unit stride...
ARTIC (Artificial Talker in Czech) is a corpusbased text-to-speech (TTS) system that enables to synthesise an arbitrary text, mainly for the Czech language. Basically, two versions of ARTIC are available—a single unit instance system (also known as fixed-inventory synthesis) with the quality of resulting speech limited by the fixed inventory, and multiple unit instance system with the quality p...
semantics, pragmatics, and discourse, among others—by the use of constrained formal-computational systems, just adequate for such modeling, has proved to be an effective research strategy, leading to deep understanding of these aspects, with implications for both machine processing and human processing. This approach enables one to distinguish between the universal and stipulative constraints. ...
the present study was carried out to investigate the replacement of soybean meal by different levels of canola meal (either with or without canola meal undergoing heat processing). two hundred forty commercial layer hens (lsl strain) at 54th week of age, selected based on the same egg production percentage and body weight. the experimental design was a crd, in a factorial arrangement of 4 repli...
Parallel data processing and parallel streaming systems become quite popular. They are employed in various domains such as real-time signal processing, OLAP database systems, or high performance data extraction. One of the key components of these systems is the task scheduler which plans and executes tasks spawned by the system on available CPU cores. The multiprocessor systems and CPU architec...
