We calculated the degree of control by cues other than the context cues by subtracting the pixel matrices of Fig. 2 d from those of Fig. 2 b, concentrating on time spent searching at F+ or F- and around L+ or L-.

If a 2 x 2 pixel matrix of dots is used to represent a single cell on the map to be printed then up to 125 different colours can be printed.

The seminal use of this technology was in the TRS-80 where the only way to get discrete pixels on the screen that could be turned on and off individually, (all points addressable) was by the use of a 2x3 pixel matrix of block graphics.

In general, this is a large pixel matrix or "frame buffer".

N(x,y) represents the new matrix resulted after applying the Convolution K to P. where P is pixel matrix.

This is essential to the proper working of all television and electronic film cameras, to avoid spatial aliasing, the folding back of frequencies higher than can be sustained by the pixel matrix of the camera.

The resulting coarse pixel matrix was output back to film.

The lateral positions of the height values depend on the corresponding object point that is imaged by the pixel matrix.

CT images were reconstructed in 512 x 512 pixel matrices using a standard convolution-backprojection procedure with a Shepp and Logan filter.

All symbols formed in an 8x8 pixel matrix, and the JR-200 could display 32 characters per line and 24 lines.
