Image conversion method and image conversion system

Abstract: The invention provides an image conversion method and an image conversion system. The image conversion system comprises an input unit, a frequency generator, an inter-frame frequency analyzer, a frequency loss detector and a frequency compensator. The input unit is used for supplying an original image with a plurality of pixels. The frequency generator is used for generating a high-frequency generating message according to a plurality of adjacent windows of each pixel by means of the difference of the adjacent windows. The inter-frame frequency analyzer is used for generating a high-frequency compensating gain message according to the original image. The frequency loss detector is used for generating a frequency loss message according to the original image. The frequency compensator is used for correcting the original image according to the high-frequency generating message, the high-frequency compensating gain message and the frequency loss message, thereby increasing high-spectrum distribution of the original image.

Conversion device for two dimensional image to three dimensional image, and method thereof

Abstract: PURPOSE: An image transformation apparatus for transforming a two-dimensional image into a three-dimensional image and a method thereof are provided to control depth information of a corresponding object as checking the depth information of a specific object selected in the two-dimensional image on a virtual three-dimensional space. CONSTITUTION: A user interface unit (120) sets a Z control point at an object selected in a two-dimensional image, and checks depth information of the selected object, and corrects the depth information of the selected object by Z-axis direction movement of the Z control point. A depth map generation unit (200) generates a depth map of the two-dimensional image, and reflects the corrected depth information of the selected object to the depth map in real-time. A three-dimensional image rendering unit (300) renders the two-dimensional image into a three-dimensional image according to the depth map, and renders the three-dimensional image whose depth information is corrected, according to the generation of the corrected depth map.

Method and device for image conversion, electronic equipment, and storage medium

Abstract: Provided in the embodiments of the present application are a method and device for image conversion, electronic equipment, and a storage medium. The method comprises: acquiring a RAW format image to be converted; inputting said image into a pretrained first network model to produce a semantic analysis result of said image, where the first network model is produced by training on the basis of marked training samples corresponding respectively to multiple first training samples, the first training samples are RAW format images, the marked training samples are RAW format images produced by marking semantic analysis results with respect to the first training samples; and determining an RGB format image corresponding to said image on the basis of the semantic analysis result of said image. As such, the image quality of the RGB format image converted from the RAW format image is increased.
