Hi Syamsundar,
As per my understanding to isolate the bubble surface and determine its Major and Minor Axis. To achieve this kindly refer to the following steps:
- Load the image and apply preprocessing by enhancing its contrast using the "imadjust" function.
- Apply thresholding to convert the enhanced grayscale image into a binary image using the "imbinarize" function. The threshold value can be determined by the "graythresh" function.
- Morphological operations, such as erosion and dilation, should be performed using the "imerode" and "imdilate" functions, respectively. These operations help refine the segmented bubble surface and remove noise or small particles.
- Conduct the connected component analysis using the "bwlabel" function to label individual connected regions in the binary image. The "regionprops" function should then be used to calculate properties for each connected component, including "Area", "MajorAxisLength", and "MinorAxisLength".
- The largest connected component, assumed to correspond to the bubble surface, is identified by finding the connected region with the maximum Area.
- Finally, the MajorAxisLength and MinorAxisLength properties should be extracted from the selected connected component, representing the bubble surface.
Refer to the MATLAB Documentation for implementation of functions:
