Target Identification Based on Intensity, Texture, and Sparse Dictionary

Abstract

Abstract It is very difficult to inspect by human at large borders and in difficult border crossings. Despite much research into the target identification, there are still challenges that make target identification difficult in the borders. Because in the borders, there is more similarity between the target and the background, and usually equipment in the borders uses maximum camouflage. This paper attempts to create an intelligent target identification software for the remote control system to identify targets based on the intensity, texture, and sparse dictionary. The input image is divided into the super-pixels by using the simple linear iterative clustering algorithm. To obtain sufficient information, the standard intensity features and Gabor texture are extracted from each super-pixel in the frequency domain. To identify the targets, several background sparse dictionaries are created. The super-pixels and the fuzzy C-means clustering are used to construct the initial dictionary. By assigning the super-pixels with the sparser representation in a dictionary, a new class is created for each dictionary. Then, these classes are used to update dictionaries. The targets are identified based on the combination of coding errors and representation coefficients. The simulation results are obtained on a database prepared by the authors. The simulation results are evaluated using Dice, specificity, sensitivity and accuracy criteria. According to the criteria, the proposed method has more successful performance than the traditional sparse representation classification method. The final performance of the proposed method is 96.8%.
