The two calibrated image stacks of grayscale-images in multilayer TIFF files are provided with embedded calibration and time of capture in the metadata.įor the use of both macro scripts and the embedded information, we recommend the use of ImageJ () or Fiji () software with versions 1.8 or above. The data related to the cases of study (i.e., calibrated image stacks), the software for image processing and analysis (i.e., either the ImageJ portable software with macro scripts or the macro scripts only), and a video tutorial showing how to obtain the water elevation at virtual wave probes using the proposed methodology, are provided. The available complementary data remain as in the version 1, which was cited in the paper. You can follow the below steps to convert gray scale image to binary image : i- read a grayscale image by importing cv2 import cv2 imgray cv2.imread pathofgrayscaleimage.png, cv2.CVLOADIMAGEGRAYSCALE) ii- convert grayscale image to binary (thresh, imbw) cv2.threshold (imgray, 128, 255, cv2. In the present version (V2) of the Mendeley repository, the reference of the paper has been updated. Water elevation measurements using binary image analysis for 2D hydrodynamic experiments, Ocean Engineering 157, 325-338. The main reason binary images are particularly useful in the field of Image Processing is because they allow easy separation of an object from the background. Numerically, the two values are often 0 for black, and either 1 or 255 for white. You should go through the documentation section on the Fiji website on. Binary images are images whose pixels have only two possible intensity values. It reads DICOM images and has a number of tools for creating binary masks. The left column will be already populated with the measured mean gray values. You can do this in ImageJ or it's new version Fiji. The ToTensor operation in PyTorch convert all tensors to lie between (0, 1). Hernández I.D., Hernández-Fontes J.V., Vitola M.A., Silva M.C., Esperança P.T.T., 2018. To calibrate the image, enter the known standard values in the right column. We will resize all images to have size (224, 224) as well as convert the images to tensor. The present data complement the paper “Water elevation measurements using binary image analysis for 2D hydrodynamic experiments”, published in Ocean Engineering (2018).
