Moreover, identity recognition, expression recognition and visitor demographic calculations are applications that can be generated through the processing of facial images. In order to perform face image processing, a face detection mechanism is needed to isolate the face area (region-of-interest-ROI). Previous research generally views facial images as unity for further processing with feature extraction techniques and recognition. This paper proposes post-processing from face detection (Viola-Jones based) to produce a bag of facial components as a data representation for the next processes which are feature extraction and recognition. The post-processing is done based on the geometric rules of the face and golden ratio to produce more accurate detection. From the experiment, the proposed method achieves 96.88% of accuracy on the development part whilst the accuracy of testing part reaches 92.52% (with precision 95.32% and recall 96.62%).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Expression recognition,Face image processing,Facial components,Feature extraction and recognition,Feature extraction techniques,Geometric rules,Region of interest,Viola jones[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]bag of facial components,face detection,geometric rule,region-of-interest,viola-jones[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICAICTA.2018.8541324[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
