Abstract: An image processing method, apparatus, and electronic device relate to the technical field of image processing. In the method, an initial image is acquired; and then a connected region in the initial image is acquired, where the connected region is a region composed of pixels having pixel values within a target threshold range in the initial image. In addition, a region of interest in the initial image is acquired according to the connected region, and the region of interest is preprocessed to obtain a target image. By extracting the region of interest in the initial image, and only preprocessing the region of interest, the resource expenditure during image preprocessing can be reduced, and the preprocessing efficiency can be improved.

The specific implementation solution is as follows: acquiring an image captured by the image acquisition device; determining a plurality of marking points on a calibration plate in the image; determining a first conversion matrix based on coordinates of each of the marking points in the image pixel coordinate system and the calibration plate coordinate system; determining a second conversion matrix based on coordinates of at least one wheel grounding point of the vehicle in the calibration plate coordinate system and the vehicle body coordinate system; and determining external parameters of the image acquisition device by using the first conversion matrix and the second conversion matrix.

Abstract: A barley male sterility gene HvMSG47, wherein the gene HvMSG47 is (i) a nucleotide sequence as set forth in SEQ ID NO: 1. (ii) a nucleotide sequence as set forth in SEQ ID NO: 2, or (iii) a nucleotide sequence that has 90% or more homology with the nucleotide sequence of (i) or (ii) and expresses the same functional protein.

Abstract: The present invention provides a novel gene WMS conferring wheat male sterility, its anther-specific expression promoter, and uses of the same. In wheat, a well-known gene Ms2 causing dominant male sterility has been widely applied in recurrent selection in China. A RNA-seq approach was performed to reveal the anther-specific transcriptome in a pair of Ms2 isogenic lines, ‘Lumai 15’ and ‘Lumai 15+Ms2’. As a result, a WMS gene was identified showing anther-specific expression at the early stage of meiosis and only in wheat carrying the Ms2 gene. The regulation of WMS could alter plant male fertility. The promoter of WMS was found to comprise anther-specific activity. Thus, the present invention might be used to achieve anther-specific gene expression, to develop male sterility in various plant species, to establish recurrent selection in various plant species, and to assist hybrid seed production.

Abstract: Circuits, methods, and apparatus that may provide power supply voltages in a safe and reliable manner that meets safety and regulatory concerns and does not exceed physical limitations of cables and other circuits and components used to provide the power supply voltages. One example may provide a cable having a sufficient number of conductors to provide power without exceeding a maximum current density for the conductors. Another example may provide a cable having more than the sufficient number of conductors in order to provide an amount of redundancy. Current sense circuits may be included for one or more conductors. When an excess current is sensed, a power source in the power supply may be shut down, the power source may be disconnected from one or more conductors, or both events may occur.
