Method of texture synthesis and image processing apparatus using the same

An image processing apparatus comprising:

• a storage medium;
• and
• a processor coupled to the storage medium, wherein the processor is configured at least for:
• generating a first single scale detail image of a plurality of single scale detail images;
• and
• generating a multi-scale detail image by blending the plurality of single scale detail images, wherein the processor is configured for generating the first single scale detail image comprising:
• performing a feature extraction of a first pixel block of an image frame to derive a first pixel feature;
• applying a first criteria to the first pixel feature to derive a positive result;
• performing a first detail alignment and a maximum extension of the positive result to derive an adjusted positive mapping result;
• applying a second criteria, which is opposite to the first criteria, to the first pixel feature to derive a negative result;
• performing a second detail alignment and a minimum extension of the negative result to derive an adjusted negative mapping result;
• and
• blending the adjusted positive mapping result and the adjusted negative mapping result to generate the first single scale detail image,
• wherein the processor is configured for performing the first detail alignment and the maximum extension of the positive result to derive the adjusted positive mapping result comprising:
• performing the first detail alignment on the positive result by applying a mapping table stored in the storage medium to the positive result to derive a positive mapping result;
• and
• performing the maximum extension on the positive mapping result by at least increasing a highest number of the positive mapping result to derive the adjusted positive mapping result.
