High dynamic range (HDR) imaging enables to immortalize natural scenes similar to the way that they are perceived by human observers. With regular low dynamic range (LDR) capture/display devices, significant details may not be preserved in images due to the huge dynamic range of natural scenes. To minimize the information loss and produce high quality HDR-like images for LDR screens, this study pr...Show More
Tone-mapping is one of the prevailing methods to overcome high dynamic range imaging limitations over low dynamic range display devices, but the tone-mapped output image may suffer from saturated regions with texture and color information loss. In this paper, a novel approach is proposed to solve the so-called clipping problem in tone-mapped high dynamic range images. A successful saturation corre...Show More
This paper proposes an effective technique for multi-exposure image fusion and visible-infrared image fusion problems. Multi-exposure fusion algorithms generally extract faulty weight maps when the input stack contains multiple and/or severely over-exposed images. To overcome this issue, an alternative method is developed for weight map characterization and refinement in addition to the perspectiv...Show More
It is arguable that whether the single camera captured (monocular) image datasets are sufficient enough to train and test convolutional neural networks (CNNs) for imitating the biological neural network structures of the human brain. As human visual system works in binocular, the collaboration of the eyes with the two brain lobes needs more investigation for improvements in such CNN-based visual i...Show More
Assessing the quality of seafood both in retail and during packaging at the production side must be carried out minutely in order to avoid spoilage which causes severe human health problems and also economic loss. Since the illnesses and decay in seafood presents distinct symptoms in different species, primarily the classification of species is required. In this field, the inadequacy of the curren...Show More
In the last decades, the electronic nose technology has been providing considerable advantages in practical applications including food and beverage quality assessment, medical diagnosis, security systems and air monitoring. Electronic nose systems include both hardware and software components. Sensors allow the system to collect gas/odor samples and the software carries out the classification pro...Show More
Automatic classification of food freshness plays a significant role in the food industry. Food spoilage detection from production to consumption stages needs to be performed minutely. Traditional methods which detect the spoilage of food are slow, laborious, subjective and time consuming. As a result, fast and accurate automatic methods need to be introduced to industrial applications. This study ...Show More
Under unsuitable sales conditions, red meat containing rich amount of protein might receive a negative perception from consumers. Importantly, nutrients lose their effectiveness, while at the same time the formation of harmful microorganisms becomes a threat to human health. The main purpose of this study is to keep the quality of the open department sales service offered to the consumers in the r...Show More
