Systems and methods for speckle reduction through bandwidth enhancement
ActiveUS6975294B2Reduce imageSpeckle reductionLaser detailsStatic indicating devicesRadiationSpeckle reduction
A laser imaging system with reduced speckle is disclosed. The laser imaging system includes spatially superpositioned 1-D arrays or alternatively 2-D arrays of independent emitters of laser radiation, with each emitter having a spectral bandwidth Δλi centered at some arbitrary wavelength λ0i. The elements of the array are allowed, by design, to have a slightly different central wavelength, thereby creating an ensemble bandwidth ΔΛ which is much greater than the bandwidth Δλi of any individual emitter in the array. The resulting increased bandwidth reduces speckle in a displayed image.

ActiveCN103927551AReduce imageImprove accuracyCharacter and pattern recognitionColor imageClassification methods
The invention discloses a polarimetric SAR semi-supervised classification method based on a superpixel correlation matrix. The polarimetric SAR semi-supervised classification method mainly solves the problem that an existing technology needs large quantity of samples. The achieving steps are as follows: (1) reading a polarimetric SAR image, conducting related preprocessing on speckle noise on the SAR image, and synchronizing a pseudo-color image; (2) calculating and testing a superpixel, training the area center of the superpixel, and constructing a data array and a physical feature correlation matrix; (3) calculating a sparsity structure feature correlation matrix through a data matrix; (4) conducting weight fusion on the physical feature correlation matrix and the sparsity structure feature correlation matrix; (5) classifying the related fused arrays through a semi-supervised method, and outputting a final classification result. The polarimetric SAR semi-supervised classification method reduces the influence of the speckle noise on the classification result, effectively reduces the requirements on the quantity of training samples, improves accuracy rate of classification, and can be used for classifying and identifying surface features.
