TL;DR: In this article, a method for generating a 3D printing file using two-dimensional image conversion is presented, which consists of a step of receiving 2D images in four directions including front, rear, left, and right sides including a target object, a step preprocessing the inputted 2D image in each direction to extract the target object from which noise is removed; a step correcting the extracted target object to equalize the size of the target objects in each directions, and extracting a number of pixels given a color for each vertical axis coordinate of the side images as depth information
Abstract: The present invention relates to an apparatus and a method for generating a three-dimensional printing file using two-dimensional image conversion. The method for generating a three-dimensional printing file using two-dimensional image conversion comprises: a step of receiving two-dimensional images in four directions including front, rear, left, and right sides including a target object; a step of preprocessing the inputted two-dimensional image in each direction to extract the target object from which noise is removed; a step of correcting the extracted target object to equalize the size of the target object in each direction, and extracting a number of pixels given a color for each vertical axis coordinate of the side images as depth information; a step of rendering the target object in each direction based on the depth information to generate a three-dimensional image; and a step of generating a three-dimensional printing file including shape information of the three-dimensional image by triangle mesh generation and slice operation.

TL;DR: In this article, the degradation of resolution and attenuation by enlarging an X-ray image is minimized by subjecting the same image to image conversion, where the electron beam is accelerated by a uniform magnetic field to form electron beam image Q1 near an anode.
Abstract: PURPOSE:To lessen the degradation of resolution and attenuation by once enlarging an X-ray image, then subjecting the same to image conversion. CONSTITUTION:An X-ray is projected onto a sample surface via a 1st X-ray optical element 12 such as X-ray condenser lens and the X-ray image obtd. therefrom is macro-imaged on an X-ray conversion part in a vacuum vessel by the 2nd X-ray optical element 15 such as X-ray objective lens. The electron beams corresponding to the X-ray image is released by a photoelectric surface 18c of the X-ray conversion part 18. The electron beam is accelerated by a uniform magnetic field to form electron beam image Q1 near an anode. The electron beam image Q1 is macro-imaged by an electron lens 20 to form an electron beam image Q2. The electron beam image corresponding to the observation image of a sample is detected by a microchannel plate 22. The attenuation of the X-ray is thereby decreased and the degradation of the resolution by the influence of an aberration is lessened.

TL;DR: In this paper, the authors propose a dynamic image conversion device that includes a means for receiving an operation signal of dynamic images from a terminal device, a mean for analyzing the received operation signal, a message decoding capability, and a coded data of the extracted frame to the terminal device.
Abstract: In the case where a terminal device reproduces a dynamic image delivers through a network, the terminal device extracts or converts to deliver only a specific frame out of the delivery stream, thereby making a fast-forwarding operation and a rewinding and reproducing operation possible. A Dynamic image conversion device includes a means for receiving an operation signal of a dynamic image from a terminal device, a means for analyzing the received operation signal, a means for requesting a delivery server that stores dynamic images to deliver a subject dynamic image, a means for receiving coded data of the dynamic image from the delivery server, a means for extracting coded data of a necessary frame from the coded data of the received dynamic image in accordance with a request of an operation signal, and a means for transmitting the coded data of the extracted frame to the terminal device.
