    • A method is to implement a Scale Invariant Feature Transform algorithm in a shared memory multiprocessing system. The method comprises building differences of Gaussian (DoG) images for an input image, detecting keypoints in the DoG images; assigning orientations to the keypoints and computing keypoints descriptors and performing matrix operations. In the method, building differences of Gaussian (DoG) images for an input image and detecting keypoints in the DoG images are executed for all scales of the input image in parallel. And, orientation assignment and keypoints descriptions computation are executed for all octaves of the input image in parallel.

    • According to embodiments of the subject matter disclosed in this application, a large audio database in a multiprocessor system may be searched for a target audio clip using a robust and parallel search method. The large audio database may be partitioned into a number of smaller groups, which are dynamically scheduled to available processors in the system. Processors may process the scheduled groups in parallel by partitioning each group into smaller segments, extracting acoustic features from the segments; and modeling the segments using a common component Gaussian Mixture model (“CCGMM”). One processor may also extract acoustic features from the target audio clip and model it using the CCGMM. Kullback-Leibler (KL) distance may be further computed between the target audio clip and each segment. Based on the KL distance, a segment may be determined to match the target audio clip; and/or a number of following segments may be skipped.

    • Development of an efficient and cost-effective doubled haploid production system and genetic transformation system are the prerequisite to initiate haploid breeding and genetic modification in flax respectively. Pre-culturing anthers on a high osmotic, high auxin and high mineral salt concentration for a period of time before transfer to a low osmotic, low auxin and low salt concentration significantly increased the overall efficiency of regeneration or anther efficiency than directly culturing anthers on a low osmotic, low auxin and low salt concentration medium. This culture procedure also dramatically reduced the frequency of shoot regeneration from somatic cells in anther culture. Using this procedure, a highly efficient anther culture-derived callus based transformation system was developed. The transformation efficiency of anther culture-derived callus based transformation system was four times higher than the best reported transformation efficiency using hypocotyls as the ex-plants in Agrobacterium tumefaciens based transformation system or particle bombardment based transformation system. The frequency of escape in anther culture-derived callus based transformation system was one third of that in hypocotyl-based transformation system using A. tumefaciens or one half using particle bombardment. This very high efficient transformation system will prove to be very valuable in basic research for gene discovery and practical applications in genetic engineering for improved traits.
