MATLAB Image Blind Detection Algorithm

In recent years, digital image blind forensics has gradually emerged as a significant research hotspot with widespread applications. The MATLAB image blind detection algorithm provides a methodological approach to identify regions within images that have been altered using Photoshop. This implementation package contains complete source code demonstrating forensic techniques such as error level analysis and lighting consistency checks, accompanied by sample detection result images for practical reference.

Furthermore, blind forensics technology for digital images holds substantial application value across multiple domains. For instance, it can be employed in digital watermark embedding and extraction to protect image copyrights, utilizing algorithms like DCT coefficient modulation. It also serves in image quality assessment through metrics like PSNR and SSIM calculations, contributing to the enhancement of image processing algorithm performance. Therefore, research and application of digital image blind forensics technology carry significant importance.
