Vimala Associate Professor, Panimalar Engineering College, India Vibu Krishnan S. U.G Student, Panimalar Engineering College, India Mathan Raj Kumar U.G Student, Panimalar Engineering College, India Ashok Kumar U.G Student, Panimalar Engineering College, India M. Janakiraman U.G Student, Panimalar Engineering College, India Object recognition is an important task in computer vision that involves identifying the objects such as digital images or videos. This research paper provides a comprehensive review of the different techniques and applications of object recognition. The paper first discusses the basic concepts of object recognition, including feature extraction and matching, classification, and detection. Next, the paper reviews the different techniques for object recognition, such as template matching, PCA-based recognition, and deep learning-based recognition. The paper then presents an overview of the different applications of object recognition, including image and video classification, object tracking, face recognition, and autonomous driving. Finally, the paper ends with a discussion of the difficulties and likely new paths for object recognition. 2023 32 38 2643 https://creativecommons.org/licenses/by/4.0/ 10.54216/JCHCI.060103 https://www.americaspg.com/journal/25/article/2643 https://www.americaspg.com/storage/11772462816.pdf
