An Improved Leaf Area Measurement Based on Image Processing
This paper concerns the plant leaf area measurement based on improved image processing.Firstly,the referenced rectangle was detected with 2-side scanning method.Then the leaf region was segmented according to 2G-R-B of every pixel with two different thresholds,and by using of dilatation operation,the trimap of leaf image was got.Next the pixels in unknown area were classified to the foreground or background area with improved knockout method and the exact leaf was segmented.Lastly,the leaf area was calculated according to the pixels proportion between leaf region and the referenced rectangle.Experiment results show this method has good accuracy and rapid speed.
