Title: Region of interest selection for object detection
Inventor: VITEK RAN
IPC: G06V10/24
Filed: 2021-02-25
Abstract: The present invention relates to a selection of regions of interest (ROI) for object detection. An object detection system can generate the ROI which can be processed by an object detector of a wide range from an input image. According to an embodiment of the present invention, the image is processed by a light neural network (for example, a heat map network) outputting object center and object scale heat maps. The heat maps are processed to define the ROI having a possibility of including objects. The overlapping ROI can be synthesized to reduce a total size of the ROI, and the synthesized ROI can be downscale to a reduced set of resolutions defined in advance. The object detectors having high accuracy and being fully convolutional can operate on the downscale ROI and output accurate detections in a part of calculations by operating on the reduced image. For example, the object detectors having high accuracy and being fully convolutional can operate on a subset (for example, the images cropped based on the ROI) of the whole image and reduce the calculations which, otherwise, may be performed on the whole input image. An object detection method includes: a step of receiving the image including the object to be detected; a step of generating a plurality of cropped images; and a step of detecting the object by applying an object detection network to each of the cropped images.

Abstract: The present invention forms an air gap of a predetermined shape. A method for manufacturing a semiconductor device includes a lamination process, an implantation process, and a desorption process. In the lamination process, a thermally decomposable organic material is laminated on the surface of the substrate on which a concave part is formed. In the implantation step, ions are implanted into the surface of an organic material laminated on the concave part. Thus, the surface of the organic material is modified to form a modified layer on the surface of the organic material. In the desorption step, when the substrate is heated to a first temperature, the organic material of the lower layer of the modified layer is thermally decomposed, and the organic material of the lower layer of the modified layer is desorbed through the modified layer. Thus, an air gap is formed between the modified layer and the concave part.
