The application of Edge Detection Algorithm Based on Rough Sets in the detection of soybean target leaf spot

To our large agricultural country, the wide variety of agricultural, the growing region and different climate characteristics, result in the different various pests in the growth periods of agricultural products. Automatic identification technology of leaves more and more used in modern agriculture. The paper applies the Edge Detection Algorithm and Image Enhancement Algorithm Based on Rough Sets of soybean target leaf spot, and gets the better result.
