In face examinations, gender classification (GC) is one of several fundamental tasks. Recent literature on GC primarily utilizes datasets containing high‐resolution images of faces captured in uncontrolled real‐world settings. In contrast, there have been few efforts that focus on utilizing low‐resolution images of faces in GC. We propose a GC method based on a pixel classifier boosting with modified census transform features. Experiments are conducted using large datasets, such as Labeled Faces in the Wild and The Images of Groups, and standard protocols of GC communities. Experimental results show that, despite using low‐resolution facial images that have a 15‐pixel inter‐ocular distance, the proposed method records a higher classification rate compared to current state‐of‐the‐art GC algorithms.
