SHV Details (cont.)

IMPROC is designed to simulate any optical component which may exist in front of the eye(s), together with the optical components of the eyeball(s). As such it provides, amongst other things:-

·

facilities for 2-D Gaussian optical blurring (specifiable in fractions of a pixel and separately definable in X & Y dimensions, if necessary),

·

means of image interpolation in 2-D using cubic spline processing (by any power of two and separately scaleable in X & Y),

·

image minification (separately in X & Y) by any integer factor - either by local blocking or by taking indexed discrete samples periodically across the image,

·

median filtering (over any odd number of pixels and separately definable for X & Y),

·

various objectively defined greyscale modifications, including inversion, greyscale expansion, 'slicing' etc.,

·

discrete sampling of an original image in n x n blocks to simulate the effects in the image sensing array due to substantial 'dead spaces' in external sampling devices (see Chapter 17 of ‘Computer Vision ...’ for some demonstrations),

·

effects of added (objectively definable) random noise added to an otherwise effectively noiseless image.
