Image Enhancement Using Guided Image Filter and Wavelet Based Edge Detection Routing Algorithm in Wireless Networks Concept

چکیده
This paper proposes a new method for image enhancement by incorporating the concept of guided image filter and wavelet based edge detection. Guided image filter is a spatial domain filter performs the filtering by considering the content of the guidance image, which can be the input image itself or another different image. Guided image filter has no gradient distortion and better performance near the edges. Wavelet based edge detection which is a frequency domain approach is used here for edge detection. It has better performance than any other edge detection methods such as Roberts, sobel operators. This method helps to suppress the noise while preserving the edges. The experimental results prove that the proposed image enhancement method outperforms other methods in both subjective and objective quality, peak-signal-to-noise ratio(PSNR). Keywords-Image enhancement, guided image filter, discrete wavelet transform, wavelet based edge detection, peak signal to noise ratio.

Optimization of Energy Consumption in Image Transmission in Wireless Sensor Networks (WSNs) using a Hybrid Method
In wireless sensor networks (WSNs), sensor nodes have limited resources with regard to computation, storage, communication bandwidth, and the most important of all, energy supply. In addition, in many applications of sensor networks, we need to send images to a sink node. Therefore, we have to use methods for sending images in which the number and volume of packets are optim...

متن کاملEdge Detection with Hessian Matrix Property Based on Wavelet Transform
In this paper, we present an edge detection method based on wavelet transform and Hessian matrix of image at each pixel. Many methods which based on wavelet transform, use wavelet transform to approximate the gradient of image and detect edges by searching the modulus maximum of gradient vectors. In our scheme, we use wavelet transform to approximate Hessian matrix of image at each pixel, too. ...
