Latest Patents

One of Zia-ur Rahman's latest patents is a smart image enhancement process. This process utilizes contrast and lightness measures to classify images as either non-turbid or turbid. For turbid images, the original image is enhanced to create a first enhanced image. If the image is non-turbid, it is classified based on a merged contrast/lightness score. If this score is poor, the non-turbid image undergoes further enhancement to generate a second enhanced image. If the second enhanced image also has a poor score, it is enhanced again to create a third enhanced image. A sharpness measure is computed for one of the images selected from the non-turbid image, the first enhanced image, the second enhanced image (if it has a good score), and the third enhanced image. If the selected image is not sharp, it is sharpened to produce a final image.

Another significant patent by Zia-ur Rahman is a system and method for the identification and quantification of sonar targets in a liquid medium. This method involves collecting a raw sidescan sonar image and separating a region of interest from it. An image transformation is performed using an extraction algorithm, and salient image characteristics are calculated. Spurious pixels are removed to obtain an extracted region of interest, and particle analysis is conducted to generate a feature vector. This vector is then presented to a neural network for classification.
