Method for improving quality of visual content, host, and computer readable storage medium

A host, comprising:

• a non-transitory storage circuit, storing a program code;
• a processor, coupled to the non-transitory storage circuit and accessing the program code to perform:
• determining a first gesture of a first hand and accordingly providing a first hand object in a visual content;
• determining a second gesture of a second hand and accordingly providing a second hand object in the visual content;
• in response to determining that the first gesture and the second gesture respectively correspond to a first predetermined gesture and a second predetermined gesture, determining a specific distance between the first gesture and the second gesture;
• and
• in response to determining that the specific distance is smaller than a distance threshold, refining the first hand object and the second hand object.

A non-transitory computer readable storage medium, the computer readable storage medium recording an executable computer program, the executable computer program being loaded by a host to perform steps of:

• determining a first gesture of a first hand and accordingly providing a first hand object in a visual content;
• determining a second gesture of a second hand and accordingly providing a second hand object in the visual content;
• in response to determining that the first gesture and the second gesture respectively correspond to a first predetermined gesture and a second predetermined gesture, determining a specific distance between the first gesture and the second gesture;
• and
• in response to determining that the specific distance is smaller than a distance threshold, refining the first hand object and the second hand object.
