查询词典 pixels

In the process of contour tracing, contour lines are gained by tracing in anticlockwise order and a method of backdate search which ensures the correctness of the algorithm is used for contour tracing at those pixels where other contour pixels can not be continuously traced. By analysis of the neighbouring pixels, this paper avoids judging those pixels that no need to be compared again.

From the mixed pixels distribution map calculated, mixed pixels mainly appear at the western coast of Bohai sea and the edges of the drift ice. Furthermore, these two areas are the areas where sea ice is fairly sparse and the mixed pixels, and therefore, easily appears at those areas. Consequently, it turns out that the method for mixed pixels detecting is effective.

A measuring system which mainly consists of a high precision motorized translation stage of one dimension, POINT GREY Flea2-14S3 CCD camera and LED light source was designed and constructed. Based on a detailed analysis for experiment results, the periodic changing law of system error of LED facula centroid location in this measuring system was found. The results indicate that based on Flea2-14S3 CCD camera, the random error of facula centroid location is about 0.018 pixels, the system error is about 0.06 pixels, and the total error is about 0.063 pixels (1/15 pixels).
