Structural health monitoring (SHM) involves the integration of sensors, smart materials, data transmission, computational power, and processing inside the structure. SHM is the process of implementing a damage detection strategy. This process involves the observation of a structure over a period of time using periodically spaced measurements, the extraction of features from these measurements, and the analysis of these features to determine the current state of health of the structural system. One such process is using image processing, the feasibility of using image processing techniques to detect deterioration in structures has been widely investigated by many researchers in the field. Keywords —.Structural health monitoring, image processing, damage. ----------------------------------------************************---------------------------------- I. INTRODUCTION All structures, including critical civil infrastructure facilities like bridges and highways, deteriorate with time due to various reasons including fatigue failure caused by repetitive traffic loads, effects of environmental conditions, and extreme events such as an earthquake. This requires not just routine or critical-event based inspections (such as an earthquake), but rather a means of continuous monitoring of a structure to provide an assessment of changes as a function of time and an early warning of an unsafe condition using real- time data. Thus, the health monitoring of structures has been a hot research topic of structural engineering in recent years. Structural sensing, Structural Health Monitoring (SHM), structural performance assessment and health prognosis are integral components of modern structural engineering practice.[7] The principal objectives of the structural health monitoring are:- i.To monitor the structural behaviour ii.To assess structure’s performance under various service loads, iii.To detect damage or deterioration and iv.To determine health or condition of the structure.[10] A five-level classification (derived from Rytter’s original four-level classification) of SHM activities is as follows: Level 1: Detection - Determining if damage is present in the structure.
