A Tool for Extraction of Objects from Digital Images
Dulal Chandra Kar, Dennis Ma · 2024
Many image processing tasks require extracting objects from one image and then combining with another image to create a new one.However, object extraction is a tedious process.A number of disadvantages can be noticed in the traditional process of object extraction.It takes a considerable amount of time and effort to outline the edges of an object before extraction and the process is not very precise, particularly for objects of irregular shapes.There are many commercial image-editing programs that provide the capability for object extraction.One of the most popular programs is Adobe Photoshop.Even though Adobe Photoshop provides a fast edge detection tool, most of the time, the edges found for an object are neither precise nor complete.Furthermore, Adobe Photoshop requires a lot of computer resource and storage to run.In this work, a tool that can be used to extract objects from digital images is presented.By using an extended and modified version of the Sobel edge detection method, the tool detects the edges of the objects in an image and outlines them in the original image.The user has the option to select any object from the outlined objects and save it in a file.The tool reduces the time needed to extract an object from an image.It has a good graphical user interface and extracts objects from an image with good precision.A user can see the original image and the image of the extracted object side by side before saving it in a separate file.
