Generating electricity using Photovoltaic Cells (PVCs) is a challenging task as photovoltic array hinges on solar irradiance, temperature and photovoltic Cells voltage (PVCsV). A maximum power point traker is indispensible to mitigate this challenging task. Developing efficient PV arrays strongly stresess to fix the operating point at MPP. In this paper, MPPT supported by Buck and Boost topologies...
Stairways region detection from a stairways image is a challenging activity to support autonomous system and visually impaired people for navigating safely. This paper proposes a framework for investigating the problem of vanishing point during stairways candidate region verification. For that, initially stairways candidate region is detected utilizing the unique natural and geometrical features of...
In continuously upgrading world, women belief in their self-worth. They have the same participation like men in almost every sector of life. But lives of women have become so vulnerable these days. Security of their lives is one of the burning questions. Everywhere they have to face unwanted incidents. Considering all the incidents towards female, this idea of Bluetooth security device aligned with...
Segmentation of images means a great matter for the medical field treatment purpose. For the extraction of brain polyps, magnetic resonance image (MRI) processing contributes in a wide range. Usually it works in two ways: white matter and gray matter. The extraction of any type of issues helps in submissions of image segmentation like in medical report analysis, in preparation of radiotherapy, in...
Tumor creates as a lopsided mass of tissues that can be condensed or liquid-filled. It can grow in any part of body. A tumor sometimes can cause to cancer as it will grow in deadly form or sometimes it doesn't mean to be like cancer or like so serious condition. Tumors have lots of names and their name have been categorized by their various shapes and their containing material. This paper is based...
In the recent years facial feature detection and recognition is an interesting and challenging work in the field of image processing in which facial region detection is the most basic step. This paper proposes a framework for detecting the facial region and facial features from a frontal facial image. Initially, an RGB facial image is used to detect the facial region. In the next step, the facial...
Zebra-crossing region detection from a zebra-crossing image is a challenging activity to support visually impaired navigating safely in outdoor environments. This paper proposes a zebra-crossing detection framework based on unique geometrical features of zebra-crossing. The unique geometrical feature is zebra-crossing stripe's edges are arranged in sorted order. Initially, pre-process the zebra-crossing...
Detecting stair region and estimating the distance from a camera to stair in a stair image is the fundamental step in the implementation of autonomous stair climbing navigation, as well as alarm systems for vision impaired people. In this paper, a framework is proposed for detecting the stair region from stair image utilizing some natural properties of stair. One unique property of them is, every...
Renewable energy using a Photovoltaic array (PVA) is becoming increasingly important in present and future world. To control the operating point to extract the maximum power (MP) from PV generator is essentially vital as the power generated by PVAs hinges on solar irradiance, temperature and PVA Voltage. To fix the MP point (MPP) of PVA, a good number of algorithms have been presented. One of them...
MVC design pattern is a well-known pattern used for architecting interactive software system. As it is partition independent, developer encourages partitioning MVC system to improve the performance. In this regard, an MVC architecture based reengineering framework is proposed in this paper. As a partition component, a pre-controller is introduced which is used some important modules. One of them is...
Solar photovoltaic (PV) arrays are a great source of generation of renewable energy. Harvesting clean energy from photovoltaic cell is reliable, pollution and noise free, low maintenance and long lasting energy source. However, typical Voltage-Current (V-I) and Power-Voltage (P-V) characteristics curves of PV cells depend on the weather conditions such as temperature and irradiation. It is always...
