Techniques for wavelet-based image disparity estimation
Various embodiments are generally directed to repeated use of wavelet filters with different directional orientations each time to detect distances to edges in different directions in deriving a disparity map from multiple image bitmaps. A method includes subjecting an image bitmap to a first-order wavelet filter a selected number of times, an orientation of the first-order wavelet filter altered each time to create a first set of intermediate maps; and subjecting the first image bitmap to a second-order wavelet filter the selected number of times, an orientation of the second-order wavelet filter altered each time to create a second set of intermediate maps; the first-order and second-order wavelet filters, as well as their orientations, selected to be mathematically related such that the first-order wavelet filter approximates a sine function and the second-order wavelet filter approximates a related cosine function, both masked by a gaussian.

Method for adjusting the oscillation frequency of a sprung balance assembly
A method adjusting oscillation frequency of a sprung balance assembly formed at random from balance springs and balance wheels. A production mechanism is set to limit a sample standard deviation of a single batch of balance springs to a predetermined maximum value, and to limit a sample standard deviation of a single batch of balance wheels to a predetermined maximum value within a given unbalance tolerance.

Apparatus and method for transmitting and receiving signal of ofdm system
A method and apparatus for transmitting an ofdm signal including converting a distribution of a signal in which inverse fourier transform is performed in an ofdm system and a method of receiving an ofdm signal including expanding a received signal are provided, and by changing a magnitude distribution of a signal that is output from an ofdm modulator to a bimodal gaussian distribution, an influence of noise in a receiving terminal can be reduced, and by limiting a signal that is output from an ofdm modulator to an appropriate magnitude, a phase in the receiving terminal can be prevented being wrongly demodulated.. .
