TL;DR: In this article, a logic operation sequence inspection is performed on input image data consisting of a group of image write instructions and a write instruction for clipping the write element of the write instructions constituting a sequent in units of logic operation sequences for superposing the pixels included in the input image.
Abstract: PROBLEM TO BE SOLVED: To perform image conversion correctly based on extra information even for input image data including any logic operation while raising the processing rate. SOLUTION: The image processor comprises a logic operation sequence inspection means 11 for analyzing input image data consisting of a group of image write instructions and specifying a write instruction for clipping the write element of the write instructions constituting a sequent in units of logic operation sequence for superposing the pixels included in the input image data, and a clip instruction creating means 12 for converting a write instruction for clipping specified by the logic operation sequence inspection means 11 into a clip instruction which can be handled independently from other write instructions.

TL;DR: In this article, an image processing method, which belongs to the technical field of image processing, has been revealed, which comprises the following steps of: inputting an original image P, and acquiring a conversion image P' by processing the P by a set image conversion method, wherein the P' only retains the size relation of grey among various pixels of the original image;
Abstract: The invention discloses an image processing method, which belongs to the technical field of image processing. The method comprises the following steps of: a) inputting an original image P, and acquiring a conversion image P' by processing the P by a set image conversion method, wherein the P' only retains the size relation of grey among various pixels of the original image; b) generating a reconstructed image R, and acquiring a conversion image R' by processing the R through the image conversion method, wherein the R' is equal to the P'; and c) taking the reconstructed image R as a result of image processing to be output. The image conversion method preferably selects an LBP transformation method. In step b, the method preferably generates the reconstructed image Rmax with maximum pixel grey and the reconstructed image Rmin with minimum pixel grey which satisfy that the R' is equal to the P', and takes the average value of the grey of various pixels in the Rmax and the Rmin as grey of corresponding pixels in the reconstructed image R. The method can be used for image processing such as image de-lighting and the like.

TL;DR: In this article, a stereo camera-based method for estimating drivable regions and a recording medium for the same is presented, which consists of an image acquisition unit which acquires a stereo image including first and second images; an image conversion unit which converts the first image into a difference map based on information about differences between the first-and second-images, an image division unit which divides the difference map into a plurality of regions based on color information, and a region estimation unit which estimates some of the regions similar to a region in which a vehicle is currently running so as to
Abstract: Disclosed are a stereo camera-based apparatus and method for estimating a drivable region and a recording medium for the same. The disclosed apparatus comprises: an image acquisition unit which acquires a stereo image including first and second images; an image conversion unit which converts the first image into a difference map based on information about differences between the first and second images; an image division unit which divides the difference map into a plurality of regions based on color information of the first image; and a region estimation unit which estimates some of the regions similar to a region in which a vehicle is currently running so as to define a drivable region. According to the disclosed apparatus, provided is an advantage in which a drivable region can be estimated without an influence of lighting or shadow. Furthermore, provided is an advantage in which a drivable region can be estimated even in an area from which a little amount of texture information is acquired due to a stereo matching error.

TL;DR: In this paper, a 50mm-diameter BSO single crystal with good properties was grown with the newly developed crystal pull-ing system, which was fabricated into an ITC device with 35×35mm2 active area and 200, um to 400μm thickness.
Abstract: Bi12SiO20 Incoherent-To-Coherent image conversion devices (abbreviated as BSO-ITC devices) are the most suitable devices for optical image processing systems, because of their high sensitivity and rather small half-wave voltage. In order to develop high storage capacity BSO-ITC devices, a 50mm-diameter BSO single crystal with good properties was grown with the newly developed crystal pull-ing system. This crystal was fabricated into an ITC device with 35×35mm2 active area and 200, um to 400μm thickness. The write-in sensitivity to produce 1/100 output intensity decay was 2, 000 erg/cm2. Modulation Transfer Function which was measured by optical Fourier transform of a coherent read-out image was 0.5 at the spatial frequency of 15-20 1p/mm. The total storage capacity was 525 1p × 525 1p and comparable to that of a high resolution vidicon.
