In this study our focus will be to develop the text highlights challenges in security surveillance, particularly the vulnerability of traditional cameras due to their visible locations, which can be exploited by criminals. To address this issue, the paper proposes an innovative solution involving hidden cameras strategically positioned to capture video through narrow regions, such as window curtain slits. The presented framework is effective and robust, automatically extracting slit regions and seamlessly merging them across frames to construct a panoramic view. The system successfully tackles challenges such as sudden illumination variations, demonstrating its effectiveness through experiments on various real video sequences. Importantly, it outperforms existing commercial software in the perceptual quality of the resulting panoramic images, showcasing the potential of this solution for enhancing security surveillance in discreet and effective ways.
