Abstract:

The traditional SPM approach based on bag-of-features (BoF) requires nonlinear classifiers to achieve good image classification performance. This paper presents a simple but effective coding scheme called Locality-constrained Linear Coding (LLC) in place of the VQ coding in traditional SPM. LLC utilizes the locality constraints to project each descriptor into its local-coordinate system, and the projected coordinates are integrated by max pooling to generate the final representation. With linear classifier, the proposed approach performs remarkably better than the traditional nonlinear SPM, achieving state-of-the-art performance on several benchmarks. Compared with the sparse coding strategy [22], the objective function used by LLC has an analytical solution. In addition, the paper proposes a fast approximated LLC method by first performing a K-nearest-neighbor search and then solving a constrained least square fitting problem, bearing computational complexity of O(M + K2). Hence even with very large codebooks, our system can still process multiple frames per second. This efficiency significantly adds to the practical values of LLC for real applications.

Proposed System:

In this paper author is apply locality constrained linear coding to identify object from images and this technique will extract features from images and then apply HOG descriptor to extract local pattern from images and generate a vector. Pattern vector will be applied on KNN algorithm to build image classification model and in this paper author is experimenting KMEANS and KNN algorithm.

Existing technique such as Bag of Features (BoF) and Spatial Pyramid Matching (SPM) is good at extracting features from images but its object classification accuracy is not satisfactory. In propose work author has describe an algorithm to extract features and then normalize and then apply HOG descriptor extract local pattern from images. Extracted pattern will be input to KNN and KMEANS to build classification model.
