the feature extraction follows image normalization; converting and quantizing the color space to obtain a color vector; for each block, the color or contour value is extracted, the formula is as follows:
the table feature classification calculation uses SVM to solve the multi-class classification problem, and uses fi(x) The i-1, 2, a, N function tests an arbitrary sample x of the image N for its class Gx as calculated by the following function:
and finally, judging whether a certain sample x belongs to the class c, firstly calculating z as phi (x), and then calculating the following decision function:
if f (z) is 1, x belongs to class c, otherwise it does not.
8. The integrated management system for 5G-based Internet of things and AI (intelligent access control) based on claim 2, wherein the AR technology block path navigation uses A-algorithm-based calculation optimization, and the calculation function formula is as follows:
cost(n)＝g(n)
f(n)＝g(n)+h(n)
where g (n) represents the back cost of the current node, h (n) represents the forward cost of the current node, but more people refer to h (n) as a heuristic function, and f (n) on the right is referred to as an evaluation function, the distance path calculation is calculated by using a manhattan distance calculation method, as follows:
D(N1,N2)＝|N1x-N2x|+|N1y-N2y|
because the manhattan distance satisfies the consistency and the characteristic of "h (gold) ═ 0", the calculation cost is low, and the calculation is simple and efficient.
