Orthogonal ratio (INTERSECTION-OVER-UNION,IOU), a concept used in target detection, is the rate of overlap between the resulting candidate frame (candidate bound) and the original marker box (ground truth bound), i.e. the ratio of their intersection to the set. Ideally, the total overlap, which is the ratio of 1.

Newton pendulum is a desktop demonstration device invented in the 1960 s. Five sphere of the same quality are fixed by the sling and closely arranged with each other. Also called: Newton swing ball, momentum conservation swing ball, permanent moving ball, physical Hitting Ball, hitting the ball and so on.

of the code segment (the location of the JPC command generated below), and generate the condition transfer JPC command (in case of 0 or false transfer). If the transfer address is unknown, enter 0. Then, call the statement processing process to process the statement or block following the then statement. After the then statement is processed, the pointer allocation position of the current Code segment should be the transfer position of the preceding JPC command. Change the jump position of the
