Embodiment Construction
[0066] The leaf edge extraction algorithm and system of greenhouse field plants based on multi-scale analysis proposed by the present invention are described in detail below in conjunction with the accompanying drawings and embodiments.
[0067] The method and system of the present invention are screened through experiments, aiming at the unsatisfactory segmentation results of greenhouse field plant leaves caused by the different shapes of greenhouse field plant leaves, complex backgrounds and overlapping each other, and the reflection of the black film of the greenhouse caused by local uneven illumination of the leaves. situation, and due to the fact that the leaves themselves have clear textures and large gradient changes, the detection of real edges is also interfered with. The present invention proposes a multi-scale analysis-based method and system for extracting edges of greenhouse field plant leaves. According to the difference of different scale spatial image informatio...
