A. System Description and Operating Procedure
Block diagram of the proposed system is shown in Fig. 2.In the proposed system there is a 2-D camera, which is mounted on the top at point 1 as shown in Fig. 2. The camera is having 12-mega pixels quality with 8 X optical zoom. After capturing images of rice seed by camera, it is stored for further processing. Two illumination sources at point 2 and 3 in Fig. 2 are used to overcome the problem of luminance and for good quality of image. Red paper can also be used for uniform distribution of light on the tray. The rice seeds are placed on the tray for capturing an image at point 4 in Fig. 2.
