[May 2012] Land Mine Detection and Image Processing By Ankush Srivastava [Email: firstname.lastname@example.org, email@example.com]Abstract: Landmines are causingenormous humanitarian and Introduction: Landmines are causingeconomic problems in many countries enormous problems in a large numberall over the world. Experts estimate of areas throughout the world todaythat up to 110 million landmines need . Landmines are a significant causeto be cleared and more than 20,000 of suffering in many developingcivilians are killed or maimed every nations. They pose a great threat toyear by landmines, with many of the individuals for years after conflict hasvictims being children . However, ceased and can be a seriouslandmine detection and clearance impediment to industrial andhave turned out to be an extremely agricultural development . Therechallenging problem. At the current are more than 100 million mines inclearance rate, it will take about 1,000 more than 70 countries . As per asyears to remove all landmines that are their purpose, mines can be classifiedalready placed and for every landmine into three types, antipersonnel minecleared, further 20 are being buried. (APM), antitank mine (ATM), andTherefore it is urgent to develop a unexploded ordnance (UXO).safe and cost efficient landminedetection system. In the past fifteenyears, various techniques, includingacoustic sensor, infrared technique,image processing techniques havebeen investigated . Landminedetection with passive infraredimages can depend quite heavily onthe environmental conditions, andthere are cross over periods when thethermal contrast is negligible and themines may be undetectable. Thiswork we deal with land minedetecting through image processing.Valuable information can be hidden inthe images.

Signal processing for landminedetection and minefield delineation detection seeks to exploittechnology is based on military discrimination information inoperational doctrine, compared to measured signals from a variety ofhumanitarian or post-conflict sensors. Signals used in minerequirements . detection are generallySignal processing is a necessary, multidimensional . The goal of thisfundamental component of all work is to detect and locate landdetection systems and can result in mines on the earth surface usingorders of magnitude improvement in image processing. This mechanismthe probability of detection and transfers low level imagereduce the false alarm rate of almost characteristics into high levelany sensor system. semantic features using image processing algorithms.Landmine-detection and ImageProcessing: Image plays vital role in Landmine-detection concept:-every aspect of business such as • Color and intensity analysis:business images, satellite images, Detection is based on object color ormedical images and so on. If we intensity contrast with theanalysis these data, which can reveal surrounding background. Theuseful information to the human users contrast threshold is defined by local
image statistics (mean and standarddeviation) of the image .• Edge detection and grouping:Straight or partly circular edges areextracted because they can indicateartificial objects. The subsequent stepgroups edges into hypotheticalartificial objects .• Polarization analysis: Objects aredetected based on their polarization Histogramcontrast with the surrounding Median Filter: In median filtering,background . first we sort the surrounding pixels ofRegardless of the type of sensor, noise desired pixel behalf of its intensityis always present . For reducing value then desired pixel will bethese types of noise we use various replaced by middle element of sortedtypes of filters. pixel values .Some neighborhood operations workwith the values of the image pixels inthe neighborhood and thecorresponding values of a sub imagethat has the same dimensions as theneighborhood. The sub image is calleda filter .In this work we introduce twofiltering methods; Median Filter and Applying Median AlgorithmWeight Median Filter; for removingthe noise. HistogramOriginal image received from sensor devices Weight Median Filter: In weight median filter, first we create weight
