Question 5 1 pts The advantage of the YCrCb colour model over the RGB representation is that: It allows more colours to be represented It allows animation It splits intensity from colour information It takes up less space Question 6 1 pts JPEG makes use of the fact that human vision is very sensitive to small variations in brightness/colour and less sensitive to the strength of high-frequency brightness changes. This means that: We can not see high-frequency changes in the image We are good at seeing small colour changes between neighbouring pixels High frequency changes appear blurred Low frequency changes appear as edges in the image

Question 7 1 pts The reason that a discrete cosine transform (DCT) is applied to image data as part of the JPEG image format is: It quantises colour information It compresses the data using lossless compression It increases the number of colours that can be stored It enables identification of high frequency edges Question 8 1 pts PNG image encoding supports which of the following? An alpha value for variable opacity Storing of vector objects with the image definition Lossy compression of image data Animation of multiple images in a single PNG file
