Abstract

Fragmented forensic image recovering from unallocated space plays an important role in computer forensics and investigation. For clear-cut investigation, it is necessary to reconstruct the recovered forensic images. Morphological operations can reconstruct the recovered images. Existing paper applies different methods to a damaged image based on structuring element, but cannot recuperate damaged image properly. This paper proposed a morphological image processing model that applies some operations like H-maxima transform, bottom-hat transformation, erosion, opening, dilation, closing operations based on structuring elements to sharp the final output image. This model can fill all holes of the damaged image properly compared to reference model. Structural Similarity Index (SSIM), Peak Signal-to-Noise Ratio (PSNR) of the proposed model is higher than the reference model. This paper applies security mechanism such as watermarking with Discrete Cosine Transform (DCT) to hide the image in the forensic workstation.
