Optical character recognition is getting more and more useful in daily life for various purposes. The aim of the paper is to find the number and English alphabets in the symbol of times new roman, arial, arial block size of 72, 48. Many researches have been done on many types of characters by using different approaches. In this recognition system was(More)
Human eye can sense different weather conditions as same as the sensor. The human eye gives good result. In this proposal work the six different edge detection methods are applied to analyze weather condition. In this work the special kind of changes in the picture for different weather condition are observed. The six different edge detection method like(More)
The present study is about the design and implementation of dip coating system based on Programmable Logic Controller (PLC) technology. The PLC correlates the operation parameters control required by the user and monitors the system during normal operation and under dipping conditions. Tests of dip coating system driven by DC motor driver and controlled by(More)
Object detection, tracking and recognition in real time is a very essential task in computer vision. There are lots of research work have been done in this area. Yet it needs to be accuracy in recognizing object. The most objective of this review is to present an overview of the approaches used and also the challenges involved. In this paper we concentrate(More)
Surface study of thin film is characterized by employing scanning Electron microscopy (SEM). The implementation of image processing algorithm is to determine the pores in the SEM images of thin film. Image segmentation is applied to detect the pores in the thin film. In this paper, ZnO thin film is used for the surface study by various edge detection(More)
Diabetic Retinopathy is one of the complicated diseases and it is caused by the changes in the blood vessels of the retina. Extraction of retina image through Fundus camera sometimes produces poor contrast and noises; detection of blood vessels in the retina is very complicated. So preprocessing is needed, in this paper a novel algorithm is implemented to(More)
The aim of the paper is to remove the noise in the images and at the same time to preserve the edges, fine details and texture in the image. This paper proposes a novel Adaptive Neuro Fuzzy Inference System (ANFIS) filter to remove impulse, Gaussian and mixed noise without affecting edges and texture of an image. It is a hybrid filter constructed by(More)
