Image Annotation via Reconstitution Graph Learning Model

الملخص EN

With great developments of computing technologies and data mining methods, image annotation has attracted much attraction in smart agriculture.

However, the semantic gap between labels and images poses great challenges on image annotation in agriculture, due to the label imbalance and difficulties in understanding obscure relationships of images and labels.

In this paper, an image annotation method based on graph learning is proposed to accurately annotate images.

Specifically, inspired by nearest neighbors, the semantic neighbor graph is introduced to generate preannotation, balancing unbalanced labels.

Then, the correlations between labels and images are modeled by the random dot product graph, to deeply mine semantics.

Finally, we perform experiments on two image sets.

The experimental results show that our method is much better than the previous method, which verifies the effectiveness of our model and the proposed method.
