Introduction

Morphological image processing has emerged as a powerful tool in the realm of image analysis, providing methods to extract meaningful information from visual data by leveraging the shape and structure of objects within an image [1,2]. Rooted in mathematical morphology, this approach utilizes a set of operations that examine the geometric properties of images, allowing for the effective manipulation of shapes and structures [3,4]. As digital imaging technologies continue to evolve, the need for advanced techniques capable of accurately interpreting complex visual data becomes increasingly critical [5]. Morphological methods offer a robust framework for addressing these challenges, facilitating applications across various domains, including robotics, medical imaging, and remote sensing [6].

The fundamental operations in morphological image processing—such as dilation, erosion, opening, and closing—are pivotal in enhancing image quality and extracting significant features [7,8,9,10]. These operations manipulate the spatial arrangement of pixels to highlight or suppress specific structures within an image [11]. By applying these techniques, researchers and practitioners can effectively isolate objects, remove noise, and refine boundaries, which was crucial for subsequent analysis and interpretation [12,13]. The choice of structuring elements plays a significant role in determining the outcome of these operations, as dictate the shape and size of the features being processed [14]. Understanding how to design and select appropriate structuring elements was essential for optimizing the effectiveness of morphological techniques [15,16].
