India is the largest producer of bananas globally, contributing to 27% of the world's banana production. As of 2020, banana production in India was 31.5 million tonnes, which accounts for 26.23% of the world's banana production. The top five countries (China, Indonesia, Brazil, Uganda and Ecuador) account for 53.47 per cent. In 2020, global banana production was expected to reach 120 million tonnes. Also, it's the second-largest produced fruit after citrus, contributing about 16% of the world's total fruit production. Edible bananas are derived from Australimusa and Eumusa series, with different origins from the same genus. Most edible bananas are cultivated mainly for their fruits; thus, banana farms generate several tons of underused by-products and waste. A lot of research has been done to improve the usage of banana by-products. Recycling these agricultural wastes proves to be of great importance as raw materials for other industries. This would prevent an ultimate loss of a vast amount of untapped biomass and environmental issues.

In the present world, biometric systems are used to analyze and verify a person's distinctive bodily or behavioral features for authentication or recognition. Till now, there are numerous authentication systems that use iris, fingerprint and face feature for identification and verification, where the face recognition-based systems are most widely preferred, as they do not require user help every time, are more automated and are easy to function. This review paper provides a comparative study between various face recognition techniques and their hybrid combinations. The most commonly used datasets in this domain are also analyzed and reviewed. We have also highlighted the future scope and challenges in this domain, as well as various Deep Learning (DL)-based algorithms for facial recognition.
