A trusted distributor of electronic and electromechanical components and automation controls. Bayer Interpolation is something that digital cameras can’t do without till the manufacturers stop quoting the multiplied resolution and quote the actual resolution like the computer LCD manufacturers. Localization taxonomy Global vs Local •Local: assumes initialpose isknown, has to only account for the uncertainty coming from robot motion (position tracking problem)•Global: initial pose unknown; harder and subsumes position tracking. Because the Bayes' filter sequentially updates the position representation, it may provide a more biologically plausible description of how position information is processed in the rat's brain. 5 octave steps) and eight orientations.
