Due to the recent challenges in access control, surveillance and security, there is an increased need for efficient human authentication solutions. Ear recognition appealing, where data acquisition procedure contactless, non-intrusive, covert. This article proposes a deep learning-based solution effective ear recognition. We explore multiple strategies enhance learning by using alternative data...

Frost formation in the heat exchangers of refrigeration systems is a well-documented phenomenon. This frost accumulation creates thermally insulating barrier that can restrict, or even block, airflow between fins, resulting decreased efficiency and degradation food products. Several methods detection defrosting have been developed, although there not an efficient mainstream method to measure co...

many researchers adopt local binary pattern for pattern analysis. however, the long histogram created by local binary pattern is not suitable for large-scale facial database. this paper presents a simple facial pattern descriptor for facial expression recognition. local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...
