Third, synthesizing the color feature and texture features, we determine and improve a similarity calculation algorithm suitable for the object region extracting algorithm before, and do the inter-image similarity matching.

During the course of developing knowledge based systems,the similarity measurement of char data type feature is often employed,and using the measurement based on Keywords,the omittance and inaccuracy of measurement is occurred.

Holospectrum series similarity matching for rotating machinery fault diagnosis

The paper regards flight maneuver evaluation as the problem of multivariate time series similarity measure,extracts the features of flight maneuver data based on SVD,and constructs the similarity matching model between two maneuvers.

Research on 3D Model Similarity Matching Based on 2D Sketch;

After introducing the system framework, the primary key techniques of content-based 3D model retrieval, including canonical coordinate normalization, geometrical shape feature extraction, appearance feature extraction, similarity measurement, query specification, user interface, and index and retrieval mechanism, are analyzed and reviewed in detail.
