CORDIC (Coordinate Rotation Digital Computer) is a method for computing elementary functions using minimal hardware such as shifts, adds/subs and compares.
CORDIC works by rotating the coordinate system through constant angles until the angle is reduces to zero. The angle offsets are selected such that the operations on X and Y are only shifts and adds.
Tracking a moving object through several frames, provided changes from frame to frame are on the order of +-(10 + "X Range") pixels in the X direction and +-(10 + "Y Range") in the Y direction is done automatically because of a relatively large area of exploration during the search for an optimal (new) position for a particular control point and a very strong force exerted by large values of the image gradient.
通過JAVA設計 GUI 界面的計算器程序,用戶可以通過鼠標依次輸入參加計算的數值,進行加、減、乘、除等混合運算,這些完成標準計算器的基礎操作。當選擇科學計算器后,可以實現sin 、 cos 、 tan 、 ln、x^y、x^2、x^3、pi、n!、mod和十六進制除這個以外還可以刪除輸入,清空結果,求1除X,X百分比,十進制是,八進制,二進制的相互轉換。
