1) The document proposes a hybrid model using scale invariant feature transformation (SIFT) and support vector machines (SVM) to classify tiger images. SIFT is used to extract local features from tiger images, which are then classified using SVM.
2) A K-means clustering algorithm is applied to SIFT features to generate cluster centers, which are used to create histograms representing tiger images. SVMs are then trained on these histograms to learn a classifier for tiger classification.
3) The proposed approach aims to enable automated surveillance of tigers by identifying and tracking individual tigers across different images. Future work involves testing convolutional neural networks for improved tiger labeling and classification.
