This paper presents a study on a multiscale pore connectivity network derived from a sandstone image. We first convert a grayscale sandstone image into pore and grain regions. The binary pore-grain image is transformed into multiscale pore by performing morphological opening operations with increasing structuring element size. https://www.roneverhart.com/HP-Victus-15-FA0031DX-15-6-FHD-IPS-Gaming-Laptop-Intel-Core-i5-12450H-3-3-GHz-GeForce-GTX-1650-8GB-DDR4-RAM-512GB-SSD/
