Image Enhancement Seminar Presentation
Image Enhancement is an method of improving the definition of a video picture by a computer program, which reduces the lowest grey values to black and the highest to white: used for pictures from microscopes, surveillance cameras, and scanners. Spatial Domain is based on the collection of pixels in the image, enhancement technique will be on noise reduction,highlighting of desired feature, neighborhood. Image Negatives using the image negative, it is easier to analyze the breast tissue. Log transformations are useful, when there is a large dynamic range for the input variable ( r ). Histograms are used to convert the pixel to density like function,and they are not unique. Applying transformations to histograms, can use results from probability.
