2.1 Image Acquisition and Pre-processing

As we know, leaves are 2+ dimensional real object and image is a colored 2D representation. The folds in leaf creates issues while capturing using simple camera devices which changes the shape information. Also while real-time capturing sometimes shadowing effect is seen on the image or flash spots, as shown in Fig. 1. This can be overcome by using some pre-processing prior to feature extraction and classification but may or may not give accurate results for every cases. Therefore, a small setup to capture real leaf images without any artificial shapes.
