Texture-Based Leaf Identification
نویسندگان
چکیده
A novel approach to visual leaf identification is proposed. A leaf is represented by a pair of local feature histograms, one computed from the leaf interior, the other from the border. The histogrammed local features are an improved version of a recently proposed rotation and scale invariant descriptor based on local binary patterns (LBPs). Describing the leaf with multi-scale histograms of rotationally invariant features derived from signand magnitude-LBP provides a desirable level of invariance. The representation does not use colour. Using the same parameter settings in all experiments and standard evaluation protocols, the method outperforms the state-of-the-art on all tested leaf sets the Austrian Federal Forests dataset, the Flavia dataset, the Foliage dataset, the Swedish dataset and the Middle European Woods dataset achieving excellent recognition rates above 99%. Preliminary results on images from the jnorth and south regions of France obtained from the LifeCLEF’14 Plant task dataset indicate that the proposed method is also applicable to recognizing the environmental conditions the plant has been exposed to.

Multiple leaflets-based identification approach for compound leaf species
Leaves of plants can be classified as being either simple or compound according to their shapes. Compound leaves can be seen as a collection of simple leaf-like structures called leaflets. However, most computer vision-based approaches describe these two leaf categories similarly. In this paper, we propose a new description and identification method for compound leaves that takes into account p...
متن کاملPlant Leaf Identification Based on Volumetric Fractal Dimension
Texture is an important visual attribute used to describe the pixel organization in an image. As well as it being easily identified by humans, its analysis process demands a high level of sophistication and computer complexity. This paper presents a novel approach for texture analysis, based on analyzing the complexity of the surface generated from a texture, in order to describe and characteri...
متن کاملLeaf epidermis images for robust identification of plants
This paper proposes a methodology for plant analysis and identification based on extracting texture features from microscopic images of leaf epidermis. All the experiments were carried out using 32 plant species with 309 epidermal samples captured by an optical microscope coupled to a digital camera. The results of the computational methods using texture features were compared to the convention...
متن کاملA Novel Method of Automatic Plant Species Identification Using Sparse Representation of Leaf Tooth Features
Automatic species identification has many advantages over traditional species identification. Currently, most plant automatic identification methods focus on the features of leaf shape, venation and texture, which are promising for the identification of some plant species. However, leaf tooth, a feature commonly used in traditional species identification, is ignored. In this paper, a novel auto...

Automatic digital plant classification and retrieval can be achieved by extracting features from its leaves. There are ample opportunities to improve plant species identification due to computerization through the designing of a convenient automatic plant recognition system. Many different approaches are used to classify the species of plants based on the plants features. In this research, the ...
متن کاملNeural Network Application on Foliage Plant Identification
Several researches in leaf identification did not include color information as features. The main reason is caused by a fact that they used green colored leaves as samples. However, for foliage plants—plants with colorful leaves, fancy patterns in their leaves, and interesting plants with unique shape—color and also texture could not be neglected. For example, Epipremnum pinnatum ‘Aureum’ and E...
