A face feature analysis which begins by generating multiple face feature candidates, e.g., eyes and nose positions, using an isolated frame face analysis. Then, a nostril tracking window is defined around a nose candidate and tests are applied to the pixels therein based on percentages of skin color area pixels and nostril area pixels to determine whether the nose candidate represents an actual nose. Once actual nostrils are identified, size, separation and contiguity of the actual nostrils is determined by projecting the nostril pixels within the nostril tracking window. A mouth window is defined around the mouth region and mouth detail analysis is then applied to the pixels within the mouth window to identify inner mouth and teeth pixels and therefrom generate an inner mouth contour. The nostril position and inner mouth contour are used to generate a synthetic model head. A direct comparison is made between the inner mouth contour generated and that of a synthetic model head and the synthetic model head is adjusted accordingly. Vector quantization algorithms may be used to develop a codebook of face model parameters to improve processing efficiency. The face feature analysis is suitable regardless of noise, illumination variations, head tilt, scale variations and nostril shape.

In the thin-film magnetic head of the present invention, the distance to a heat-generating layer is shorter from the end part on the side facing, a recording medium in a magnetoresistive device than from the end part on the side facing the recording medium in an electromagnetic transducer. Therefore, even when the thin-film magnetic head tilts so that its electromagnetic transducer side approaches the recording medium when floating up from the recording medium, the amount of thermal expansion caused by the heat from the heat-generating layer is greater in the magnetoresistive device than in the electromagnetic transducer. This reduces the gap between the magnetoresistive device and the recording medium, whereby a high reproducing output can be obtained.
