Convert PGM to KERNEL

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.

The KERNEL file extension, associated with Morphology Kernel Image, stands for "Kernel Image File". It defines structuring elements for morphological operations like erosion, dilation, opening, and closing in image processing. These operations are crucial for tasks such as image segmentation, object detection, and noise removal. Originating in the 1960s with mathematical morphology, the KERNEL file encapsulates the shape and size of the structuring element, influencing the results of these operations.
