Binärbild

A Binärbild, or binary image, is a digital image that consists of only two distinct pixel values. These values are typically represented as black and white, though they can also be interpreted as 0 and 1, or any other two contrasting colors. In essence, a binary image is a simplified representation of an image where each pixel is assigned to one of two categories.

The creation of a binary image often involves a process called thresholding. In this process, a threshold value is chosen. Pixels with intensity values above this threshold are assigned one value (e.g., white), while pixels with intensity values below or equal to the threshold are assigned the other value (e.g., black). This method is commonly used for converting grayscale or color images into a format suitable for certain image processing tasks.

Binary images are fundamental in various fields, including optical character recognition (OCR), where they help in distinguishing text from background, and in medical imaging for segmenting structures. Their simplicity makes them computationally efficient for storage and processing, and they are particularly useful for tasks that require clear separation of foreground and background elements. Despite their limited color depth, binary images can effectively represent shapes, outlines, and patterns.
