Speckle detection method and electronic device

A speckle detection method, comprises:

• obtaining a to-be-detected image;
• converting the to-be-detected image into Lab color space to obtain a Lab image;
• extracting a speckle feature from the Lab image to obtain a speckle feature image, wherein the speckle feature image comprises a skin speckle feature and a subcutaneous speckle feature;
• and
• determining a skin speckle and a subcutaneous speckle in the speckle feature image.

An electronic device, comprising:

• a non-transitory memory comprising instructions;
• and
• a processor coupled to the non-transitory memory, the instructions being executed by the processor to cause the electronic device to:
• obtain a to-be-detected image;
• convert the to-be-detected image into Lab color space to obtain a Lab image;
• extract a speckle feature from the Lab image to obtain a speckle feature image, wherein the speckle feature image comprises a skin speckle feature and a subcutaneous speckle feature;
• and
• determine a skin speckle and a subcutaneous speckle in the speckle feature image.

A computer program product for speckle detecting, the computer program product being embodied in a non-transitory computer readable medium and comprising computer instructions for:

• obtaining a to-be-detected image;
• converting the to-be-detected image into Lab color space to obtain a Lab image;
• extracting a speckle feature from the Lab image to obtain a speckle feature image, wherein the speckle feature image comprises a skin speckle feature and a subcutaneous speckle feature;
• and
• determining a skin speckle and a subcutaneous speckle in the speckle feature image.
