Abstract This paper proposes image modification of seedlings in rice growing area, using fuzzy’s method. Parachute planting was seedlings Inspection. Image processing method and fuzzy singleton rule were used together to contrast enhancement and to lessen an incorrect image when comparing to an original image. This article demonstrated an initiation of fuzzy rule to adjust image resolution especially in each pixel of gray image. Such adjustment stipulated membership graph of image and then compared to histogram equalization (Yu, W., Qian,C., & Bao-Min,Z.,1999). And Linear Grey Level Mapping (YeongTacg,k.,1997). The result showed that better image adjustment belonged to presented fuzzy rule. An original image from fuzzy rule’s process showed lesser an incorrect image and could be used to develop an original image for nondestructive inspection equipment
