DEVICES INCORPORATED
Image Resampling Sequencer
DESCRIPTION
The LF2301 is a self-sequencing address generator designed to filter a two-dimensional image or remap and resample it from one set of Cartesian coordinates (x,y) into a new set (u,v). The LF2301 can resample digitized images or perform such manipulations as rotation, panning, zooming, and warping as well as compression in real-time. By using two LF2301s in a Image Transformation System (ITS), nearest-neighbor, bilinear interpolation, and cubic convolution algorithms, with kernel sizes up to 4 x 4 pixels, are all possible (see Figure 1). This system can also implement simple static filters with kernel sizes up to 16 x 16 pixels.
