Abstract
Digital camera is very popular and the number of digital photos grows exponentially.aced to huge number of photos, the collection and selection ofhotos becomes a big problem.hoto composition means the placement of camera and the selection ofhe field of view. It determines whether objects should be placed inside thehoto or be excluded outside. Most people agree that photo compositionlmost determines whether a photo is good or not. Therefore, our research isocus on photo composition. This problem is subjective and relates to humanisual perception. Although this problem is subjective, it is fortunate thatrom the experience accumulated by photographers in recent years, certainommon rules were extracted. We select the rules that have clear definitionnd suitable for automatic quantitative analysis to pick out bad photos or toake recommendations and scores.t is said that a not very good photo after doing a good cropping will let ahoto turn from death into life. The performance of digital camera nowadayss more and more powerful and image resolution is higher and higher, ando images can be cropped without serious loss of resolution. Our results inutomatic cropping support this observation.ur preliminary results for 132 photos are based on five rules (the horizon,hoto balance, location of main object, revealing line patterns and shapes,nd avoiding mergers), and the precision of each rule is 71%, 96.8%, 73.1%,8.4%, and 71.4%, respectively.
