In this paper, a new tuning algorithm for PID controller based on gain margin and phase margin concept is proposed. The controller parameters are dependent on single parameter, which are subjected to a desired phase margin, and a minimum required gain margin constraint. The main advantage of the proposed tuning algorithm with respect to previous works is that it is easy to implement. Moreover the...
Standard Gaussian mixture modeling (GMM) is a well-known method for image segmentation. However, the pixels themselves are considered independent of each other, making the segmentation result sensitive to noise. To reduce the sensitivity of the segmented result with respect to noise, Markov random field (MRF) models provide a powerful way to account for spatial dependences between image pixels. However,...
In this paper, we present a efficient algorithm for real-time ellipse detection. Unlike Hough transform algorithm that is computationally intense and requires a higher dimensional parameter space, our proposed method reduces the computational complexity significantly, and accurately detects ellipses in realtime. We present a new method of detecting arc-segments from the image, based on the properties...
