Abstract :Digital image processing heavily relies on the connectivity of pixels, as it is a vital component for accurate object identification and analysis within an image. Grouping together pixels with similar features such as colour and intensity, allows for the formation of meaningful patterns or objects, which is essential for object recognition and segmentation. This approach is particularly valuable in photogrammetric imaging, video surveillance, deep learning as it facilitates the isolation of regions of interest and object tracking. Image smoothing is also a crucial aspect in enhancing visual quality by reducing noise and enhancing details, especially in applications such as aerial mapping, medical imaging, video compression, image resizing and computer vision. The absence of connected pixels and image smoothing would make image processing tasks more challenging and less reliable, making them fundamental to digital image processing and critical to various applications in diverse fields. This paper introduces a novel image smoothing filter called Connected Pixels Based Image Smoothing Filter insert ignore into journalissuearticles values(CPF);, which is based on gray connected pixels. The success of the CPF was compared to that of the Non-Local Means Filter insert ignore into journalissuearticles values(NLMF); in terms of Structural Similarity Index insert ignore into journalissuearticles values(SSIM); for the same Mean Squared Error insert ignore into journalissuearticles values(MSE);. The experimental results showed that CPF has a better ability to preserve image details compared to NLMF.
