Provided is a method of and apparatus for video encoding and decoding based on motion estimation. The method includes generating a motion vector by searching a reference picture using pixels of a current block, generating a prediction motion vector that is a prediction value of the motion vector by searching the reference picture using previously encoded pixels located adjacent to the current block, and encoding the current block based on the motion vector and the prediction motion vector. By accurately predicting the motion vector of the current block, the number of bits required for encoding the motion vector can be reduced, thereby improving the compression rate of video data.

Kalman filter processing is applied to each of successive images of a scene obscured by fog, captured by an onboard camera of a vehicle. The measurement matrix for the Kalman filter is established based on currently estimated characteristics of the fog, and intrinsic luminance values of a scene portrayed by a current image constitute the state vector for the Kalman filter. Adaptive filtering for removing the effects of fog from the images is thereby achieved, with the filtering being optimized in accordance with the degree of image deterioration caused by the fog.

Efficient multiview video encoding is realized even in a situation in which a processing picture cannot be obtained, by accurately estimating a motion vector and simultaneously using an inter-camera correlation and a temporal correlation in prediction of a video signal. A view synthesized picture at a time when a processing picture has been taken is generated from a reference camera video that has been taken by a camera different from a processing camera that has taken the processing picture included in a multiview video based on the same setting as that of the processing camera. A motion vector is estimated by searching for a corresponding region in a reference picture taken by the processing camera using a picture signal on the view synthesized picture corresponding to a processing region on the processing picture without using the processing picture.

A method of super resolution-based deintelacing processing in interlaced video sequences is provided. Block matching is applied on each image block to obtain a motion vector MV. Using MV as the initial motion vector, optical flow is applied on that block to obtain a sub-pixel resolution motion vector OF. Missing pixels are then interpolated using motion vector OF and one or more images in the sequence.

A video decoding method performed by a decoding apparatus comprises: deriving control points (CPs) for the current block; obtaining motion vectors for the CPs; deriving a motion vector of a sub-block or a sample unit in the current block on the basis of the obtained motion vectors; deriving a prediction sample for the current block on the basis of the derived motion vector; and generating a reconstruction sample on the basis of the prediction sample. The method enables effective performance of inter prediction through the motion vectors (transformation prediction), not only when an image in the current block is moved in a plane, but also when the image in the current block is rotated, zoomed in, zoomed out, or transformed into a parallelogram. Accordingly, the amount of data for the residual signal for the current block can be eliminated or reduced, and the overall coding efficiency can be improved.

A hi-hat type electronic pad capable of detecting, with reality, an up-and-down motion of a movable pad body that operates similarly to a top cymbal of an acoustic hi-hat, and capable of accurately detecting the operation by one of operation switches which is depressed by a corresponding actuator, even if the movable pad body is moved downward in an inclined state. An operation detecting unit includes a base plate and an elastic member and is provided on an HH pad body. When the HH pad body is moved downward by a pedal operation, the actuators formed on an upper surface of the elastic member and corresponding sheet switches disposed on the base plate are made in contact with one another, whereby operation ON is detected. The sheet switches are formed into an annular shape as viewed in plan.

Inter-field-interpolation spatial transition is calculated based on the sum of absolute values of differences between pixel values of an inter-field-interpolated pixel and adjacent pixels on the same field. Inter-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of the inter-field-interpolated pixel and pixels at corresponding positions on previous delayed field and present field. Intra-field-interpolation temporal transition is calculated based on the sum of absolute values of differences between pixel values of an intra-field-interpolated pixel and the pixels at the corresponding positions on the previous delayed field and the present field. The amounts of error in the interpolated pixels are calculated based on information of the inter-field-interpolation spatial transition, inter-field-interpolation temporal transition, and intra-field-interpolation temporal transition, and a pixel is generated by switching between inter-field interpolation and intra-field interpolation accordingly.

A sole assembly is provided including multiple compression units entrapped in a midsole and adjacent an outsole to efficiently distribute forces and to assist in correct foot motion during a gait cycle. The multiple compression units can be linked to one another to assist the foot in moving through an appropriate foot motion during a gait cycle. A heel compression unit can be linked to an arch compression unit, which can be linked to one or more forefoot compression units, which can be linked to a toe compression unit. The linking of the heel compression unit, the arch compression unit, and the forefoot compression unit to one another can resist torsional movement of the units between one another, thereby providing a more stable foot support, while still providing impact-attenuation and force distribution through the sole assembly.

A frame interpolation apparatus generates a pixel value at an interpolation position by examining pairs of pixel blocks, one from a preceding reference frame and one from a following reference frame, located in positions that are point-symmetric or nearly point-symmetric with respect to the interpolation position. The pair of pixel blocks showing the greatest mutual similarity is selected, the central pixels in the selected pair of pixel blocks are taken as reference pixels, and the interpolated pixel value is generated from the reference pixel values. By routinely examining a large number of pairs of pixel blocks for each interpolation position, the frame interpolation apparatus can detect image motion accurately and generate accurate interpolated values.
