Semi-automatic photograph tagging by combining context with content-based information

Highlights：

• We propose a semi-automatic technique for the annotation of people in photographs.

• The technique uses context and content information and is based on the weighted sum of estimators.

• Multivariable linear regression and slope functions are adopted to weight the estimators.

• The technique obtained better results than the context-based and content-based methods when the metric H-Hit rate was used.
