PDF-Lab Convolution EE ContinuousTime Linear Systems Dep

1 Introduction In this lab you will review the concept of convolution and learn how to convolve signals in matlab Because you are working on a computer you are necessarily working with 64257nitelength discretetime versions of continuoustime signals. They are in some sense the simplest operations that we can perform on an image but they are extremely useful Moreover because they ar e simple they can be analyzed and understood very well and they are also easy to impleme nt and can be computed ver It is the single most important technique in Digital Signal Processing Using the strategy of impulse decomposition systems are described by a signal called the impulse response Convolution is important because it relates the three signals of intere e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations The convolution property forms the basis for the concept of filtering which we explore in this lecture Our objective here is to provide some feeling for what filtering means and in very simple terms how it might be implemented The concept of filteri Jitendra. Malik. Different kinds of images. Radiance images, where a pixel value corresponds to the radiance from some point in the scene in the direction of the camera.. Other modalities. X-rays, MRI…. They replace the value of an image pixel with a combination of its neighbors. Basic operations in images. Shift Invariant. Linear. Thanks to David Jacobs for the use of some slides.
