Methods and systems are disclosed to realistically simulate facial wrinkle aging of a person using a neutral state (natural look) image and one or more expression images (e.g., smile, frown, pout, wink) that induce wrinkles. The neutral and expression images are processed to simulate wrinkle aging by registering the wrinkles that are visible in the expression image onto the neutral image, thereby generating a wrinkle-aged simulated image. Advantageously, a person's own wrinkle histological data is utilized, hence providing an accurate and realistic wrinkle aging simulation. Similarly, the neutral image is processed to eliminate all visible wrinkles thereby generating a wrinkle de-aged simulation image. Additionally, blending of a neutral image with an aged or de-aged simulation image is disclosed, where the degree of blending is based on statistical modeling of skin condition with age and / or expected outcome of a particular type of treatment. The methods and systems disclosed have wide applicability, including, for example, areas such as dermatology, cosmetics and computer animation, among others.

When an engine stop control is executed while an automatic ratio shift portion is in a neutral state, a switching clutch is operated, so that a differential portion carrier of a differential portion planetary gear device that is linked to an engine, and a differential portion ring gear linked the automatic ratio shift portion are integrally rotated. Therefore, along with the engine stop control, the rotation speed of the rotating elements of the differential portion planetary gear device is reduced while the rotating elements are integrally rotated or substantially integrally rotated. Since the rotating elements are rotated integrally or substantially integrally, the high rotation speed of the differential portion ring gear linked to the automatic ratio shift portion, which tends to have a heightened rotation speed particularly during the neutral state, is prevented.

A mode switching controlling device and method switches a hybrid drive (HEV) mode to an electric drive (EV) mode without engine stoppage shock. A fourth-to-fifth speed upshifting command is generated due to reduction in an accelerator opening. Then, an HEV-to-EV-mode switching command is generated. A command pressure of a direct clutch is set to 0, and an actual-pressure reduction disengages the direct clutch, causing an automatic transmission to be in a neutral state. When a first time elapses from generation of the switching command, a first clutch command pressure is set to its maximum value, and the first clutch disengages by an actual pressure increase. When a second time elapses, the engine is stopped by reducing engine torque to perform mode switching. A front brake command pressure is set to a precharge pressure when the second time elapses and to its maximum value at a later time when a gear-switching rotation matching controlling operation of a motor-generator is ended, so that the front brake is engaged due to an actual pressure increase for upshifting from the fourth to fifth speed.
