Abstract: An optimization method, an optimization system for computer programming code and an electronic device using the same are provided. The optimization method includes the following steps. Several optimizers each having several branch paths are provided. A counter is set on each of the branch paths. When the optimizers run through the branch paths, the counters set on the branch paths, where the optimizer run through, are counted. The computer programming code is compiled through the optimizers. Several count values of the counters are obtained. The count values are collected to obtain a feature vector of the computer programming code. The feature vector is inputted to a machine learning model to obtain an optimizer collection suitable for the computer programming code.

Abstract: An image processing method includes: performing an equirectangular projection on a first fisheye image and a second fisheye image to obtain a first equirectangular image and a second equirectangular image; swapping positions of a left-half image of the second equirectangular image and a right-half image of the second equirectangular image to obtain a third equirectangular image; rotating the first equirectangular image and the third equirectangular image by 90 degrees in a spherical coordinate system to obtain a first rotated image and a second rotated image; stitching the first rotated image and the second rotated image to obtain a stitched image; and rotating the stitched image by ?90 degrees in the spherical coordinate system to obtain a panoramic image.
