By accessing and modifying the pixel values in the image matrix, you can apply custom transformations and create stunning visual effects or extract valuable information from the image data.

Setting Threshold Intensity for Identifying Defects

When working with TIFF files in MATLAB, it’s essential to set a threshold intensity level to accurately identify defects within the image. The threshold intensity serves as a cutoff point that distinguishes between defects and non-defects, enabling effective defect detection and analysis.

MATLAB offers various thresholding techniques to help you set the threshold intensity. These techniques include global thresholding and adaptive thresholding, which allow for automatic or manual determination of the intensity level. By adjusting the threshold intensity, you can customize the detection process based on the specific characteristics of the image and the defects you are interested in targeting.

“Setting the threshold intensity is a critical step in defect identification and analysis. By carefully selecting the appropriate intensity level, you can ensure accurate detection and minimize the risk of false positives or false negatives.”
