NGC 6543 PR95-01 ST SCIOPO - January 1996 - P. Harrington (U.MD), NASA HST.WFPC2 12/9/94 29
EE434 - Project 1 Image Processing Load the image NGC using the MATLAB function imread. (a) Display (show) the image using the command imshow. (b) What is the image format or extension (JPG, TIF, GIF, PNG, ...)? (C) What is the color type of the image (grayscale, truecolor (RGB), or indexed)? a) Find the size of the image matrix. How many rows are in the image matrix (height of the image)? How many columns (width of the image)? Comment on your answer. (e) How many pixels in the image? (1) How many bits per pixel (bit depth) are needed to store an uncompressed version of the image? (e) How many bits are needed to store an uncompressed version of the image? (h) What is the compression ratio used in storing the image on the computer? () Write the MATLAB commands to create a new image (subimage) that consists of the top half of the NGC image. Write the MATLAB commands to create a new image (subimage) that consists of the right half of the NGC image. Hint: use the MATLAB function imfinfo,
