概要 Newly developed method of image processing was applied to measurement of the root length. The image of cucumber root system was taken by still video camera, and the root length was calculated on the b...asis of the counting operation of connected pixels in the thinned root images obtained from the image processor. Reliable estimations of thread length were provided with the designed counting technique. Estimation error was within 2% of actual length and the correlation coefficient between actual and estimated lengths was 0.9999 (P<0.01).続きを見る
