This work investigates computational frameworks for determining the optimal weighting and combination of diverse visual features to enhance multiclass object classification.
Compared multiple kernel learning algorithms against lightweight baseline weighting strategies.
Formulated boosting-inspired ensemble techniques designed for direct extension to multiclass classification settings.
Evaluated models across visual classification benchmarks using descriptors for shape, color, and texture.
Simple baseline methods proved highly competitive with multiple kernel learning while operating orders of magnitude faster.
Boosting-type ensemble models consistently generated superior classification accuracy compared to all alternative methods across every experimental evaluation.
