Improving Images Using AV Thresholding
AV thresholding stands as a fundamental technique within the realm of image enhancement. It leverages the concept of partitioning an image into distinct regions based on pixel intensity values, effectively highlighting specific features or objects. By establishing a predefined cut-off point, pixels above this threshold are classified as foreground while those below are categorized as background. This process not only simplifies the image but also enhances its overall visual appeal by emphasizing areas of interest. AV thresholding finds diverse applications in various fields, including medical imaging, object detection, and document analysis.
- Applying AV thresholding involves a systematic approach that begins with the selection of an appropriate threshold value. This value can be determined empirically through visual inspection or by employing more sophisticated algorithms. Once the threshold is established, each pixel in the image is compared against this value. Pixels exceeding the threshold are assigned a specific representation, while those below are assigned a corresponding background color or value.
- , Upon completion of this step, the image undergoes segmentation, where pixels with similar intensities are grouped together. This segmentation facilitates the isolation and analysis of objects or regions of interest within the image.
