Thresholding is a technique used in image processing to create binary images by converting grayscale images into black and white images. This process involves setting a threshold value, which determines the dividing point between the two colors. Pixels with intensity values above the threshold are assigned one color (typically white), while those below are assigned the other color (typically black). The choice of threshold value is crucial and can significantly affect the outcome of the image. There are several methods for determining the threshold, including manual selection, histogram-based methods, and adaptive thresholding. Manual selection involves choosing a threshold value based on visual inspection, while histogram-based methods analyze the distribution of pixel intensities to determine an optimal threshold. Adaptive thresholding, on the other hand, calculates different thresholds for different regions of the image, which can be useful for images with varying lighting conditions. Thresholding is widely used in various applications, such as optical character recognition (OCR), object detection, and medical imaging, where binary images are often required for further analysis.
