Neste trabalho, Compressed Sensing é introduzido do ponto de vista da Física Estatística. Após uma introdução sucinta onde os conceitos básicos da teoria são apresentados, incluindo condições necessárias para as medições e métodos básicos de reconstrução do sinal, a performance típica do esquema Bayesiano de reconstrução é analisada através de um cálculo de réplicas exposto em detalhe pedagógico. Em seguida, a principal contribuição original do trabalho é introduzida --- o algoritmo Bayesiano de Compressed Sensing Online faz uso de uma aproximação de campo médio para simplificar cálculos e reduzir os requisitos de memória e computação, enquanto mantém a acurácia de reconstrução do esquema offline na presença de ruído aditivo.
