This volume constitutes the refereed proceedings of the 4th International Conference on Recent Trends in Image Processing and Pattern Recognition, RTIP2R 2021, held in Msida, Malta, in December 2021. Due to the COVID-19 pandemic the conference was held online. The 19 full papers and 14 short papers presented were carefully reviewed and selected from 84 submissions. The papers are organized in the following topical sections: healthcare: medical imaging and informatics; computer vision and pattern recognition; document analysis and recognition; signal processing and machine learning; satellite imaging and remote sensing. 

Various problems towards the development of Indian Postal Automation (IPA) system is discussed here. More specifically, in this endeavor, some of the tasks such as, statistical analysis of Indian postal documents, bi-lingual pin code digit recognition, script identification prior to city name recognition, and Dynamic Programming (DP) based city name recognition of Bangla script are the major contributions of this work. The feature sets considered  for the work consists of Structural and Statistical features, Normalized binary pixel images, Direction code based features, Gradient based features etc. For recognition, two categories of classifiers, viz., Multi Layer Perceptron (MLP) and Modified Quadratic Discriminant Function (MQDF) based classifiers have been selectively tested here and detailed results are presented.
