作者：
Highlights：
• Novel quaternion shifted-Gegenbauer moments of fractional-order are derived.
• The proposed moments ignore image mapping/interpolation as required by circular moments.
• Quaternion shifted-Gegenbauer moment invariants of fractional orders are derived.
• The FrQSGMs descriptors show excellent robustness to various kinds of noise.
• The FrQSGMs descriptors show high recognition ability of similar color objects under various attacks.
