Abstract: A method and apparatus for data augmentation based on outpainting is proposed. The method includes receiving input of image information and prompt information by an image processing apparatus, creating training data by using outpainting techniques and performing the data augmentation on the basis of the image information and the prompt information by the image processing apparatus, training an object detection model on the basis of the created training data by the image processing apparatus, evaluating performance of the object detection model by the image processing apparatus, and converting and storing performance evaluation results and the prompt information into a database by the image processing apparatus.

Abstract: A scroll compressor having a vacuum preventing structure includes: a casing forming a receiving space therein; a fixed scroll fixed to a main frame installed in the casing, and including a back pressure passage at an outer side surface thereof, a discharge pressure hole formed at one side of the back pressure passage such that the back pressure passage and a discharge pressure space of the casing can communicate with each other, a middle pressure hole formed at another side of the back pressure passage such that the back pressure passage and a compression space of the casing can communicate with each other, and a suction pressure hole formed at still another side of the back pressure passage such that the back pressure passage and a suction pressure space can communicate with each other; an orbiting scroll positioned between the fixed scroll and the main frame and forming a compression space by being coupled with the fixed scroll; a piston slidably installed in the back pressure passage, for opening or closin

Abstract: Disclosed herein is a scroll compressor, and more particularly, a fixed scroll of the scroll compressor which can allow part of gaseous refrigerant to be smoothly introduced into a compression chamber while preventing introduction of the remaining gaseous refrigerant that is heated in the compressor. The fixed scroll includes a scroll body having an involuted wrap to define a compression chamber therein and provided, around a lower end thereof, with a mounting flange to be arranged on an upper surface of a main frame, and an interceptive suction portion configured to guide part of the gaseous refrigerant, that is directed upward along the main frame, into the compression chamber while preventing introduction of the remaining gaseous refrigerant that is circulated around the scroll body.
