Keywords: Convolution, Gaussian filter, Laplacian filter
The document contains methodology and manifest results of application of 2D convolution in digital image processing using MATLAB, and how different filters respond in image filtering brightening and smoothing along with edge detection and enhancement in a particular gray scale image. filters used in the research are Averaging, Gaussian and Laplacian filter, where Averaging and Gaussian filters are used mainly for image smoothing and noise reduction and Laplacian filter is used for edge detection and enhancement. Section I gives the introduction to the basis of convolution in 1D. Section II gives information and basic idea of 2D convolution in image processing Section III and IV relates to the function of filters used and their results obtained. Section V and VI delivers analogy of image detection and edge enhancement and Section VII concludes the entire research paper followed by the references.
