Method and system for defect detection in image data of a target coating

A system comprising:

• a database;
• and
• a processor programmed for communication with the database, the processor programmed for:
• receiving from an image capturing device at least one digital image of a target coating, each digital image being obtained at a different angle with respect to a surface of the target coating;
• performing, in operative connection with at least one filtering unit, a first image analysis on the obtained at least one digital image to determine at least one bright region within the at least one digital image by isolating image foreground data from image background data;
• performing a blob analysis to determine at least one corrupt area within the at least one bright region;
• and
• if at least one corrupt area is found,
• masking out the at least one corrupt area for further analysis of the at least one digital image, or
• rejecting the at least one digital image, and/or
• initiate a repetition of the image capturing.

A non-transitory computer program product having instructions that are executable by a computer, the computer program product comprising instructions to:

• receive from an image capturing device at least one digital image, each digital image being obtained at a different angle with respect to a surface of a target coating;
• perform, in operative connection with at least one filtering unit, a first image analysis on the obtained at least one image to determine at least one bright region within the at least one image by isolating image foreground data from image background data;
• perform a blob analysis to determine at least one corrupt area within the at least one bright region;
• and
• if at least one corrupt area is found, to
• mask out the at least one corrupt area for further analysis of the at least one image, or
• reject the at least one image and/or
• initiate a repetition of the image capturing.
