Plant leaf disease detection and classification is one of the interesting research areas in the agriculture sector. An approach based on image processing and machine learning techniques is proposed in this paper to detect and classify paddy leaf diseases. Leaf Blast, Brown Spot and Bacterial Leaf Blight diseases are considered to calculate the perf...

We present a novel approach to the design of codebooks in patch-based, bag-of-feature visual scene recognition problems. The Sequential Input Space Carving (SISC) approach we present achieves compact codebooks in a fraction of the computation time needed by the k-means clustering method usually employed in this setting. We demonstrate the performan...

The well known framework in the object recognition literature uses local information extracted at several patches in images which are then clustered by a suitable clustering technique. A visual codebook maps the patch-based descriptors into a fixed-length vector in histogram space to which standard classifiers can be directly applied. Thus, the con...
