Semi-supervised learning for refining image annotation based on random walk model

作者:

Highlights:

• A unified framework for refining annotation by fusing GMM with random walk.

• A semi-supervised learning is used to enhance the quality of training data.

• Gaussian mixture model is learned to estimate initial annotations.

• Integrating label and visual similarities of images associated with the labels.

• Random walk is implemented on graph to further mine the semantic correlation.
