Abstract: An image processing device may perform a method for generating 3D HDR radiance fields, and the method may include: receiving an input of low dynamic range (LDR) images, which are captured at various viewpoints; constructing the 3D high dynamic range (HDR) radiance fields from the LDR images captured at the various viewpoints; generating an HDR image by ray marching on a basis of the 3D HDR radiance fields; generating a tone-mapped LDR image from the HDR image through a tone mapping module; calculating a loss value on a basis of the LDR images captured at the various viewpoints and the tone-mapped LDR image; and modifying parameters of the 3D HDR radiance fields and parameters of the tone-mapping module, so as to maximally minimize the loss value. The LDR images captured at the various viewpoints may be images captured under photometric conditions different from each other.

Abstract: The present disclosure relates to a nitric oxide-sensitive hydrogel. The hydrogel is formed through in-situ hybridization in a target site by means of a click chemical reaction and is prepared using a nitric oxide-sensitive crosslinker. The hydrogel can effectively collect and scavenge nitric oxide overexpressed in the target site, and a drug loaded in the hydrogel can be locally and sensitively released to a target site to be treated. Therefore, the hydrogel can be effectively used to prevent and treat inflammatory disease caused by the overexpression of nitric oxide.

Abstract: An electronic device using a spatio-temporal self-similarity (STSS) and a method of operating the electronic device are disclosed. The electronic device may generate an STSS tensor including a spatial self-similarity map and spatial cross-similarity maps for each position of a video feature map corresponding to an input video based on a temporal offset and a spatial offset. STSS feature vectors may be generated from the STSS tensor by decreasing a dimension of the spatial offset and maintaining a dimension of the temporal offset for each position of the STSS tensor. An STSS feature map may be generated by integrating the dimension of the temporal offset for each position of the STSS feature vectors. An inference on the input video may be based on a result of adding the STSS feature map to the video feature map.

Abstract: There is provided an analog-stochastic converter for converting an analog voltage signal into a pulse signal having a corresponding probability. The analog-stochastic converter is implemented using a threshold switching element and a simple logic circuit, thereby reducing a size of the analog-stochastic converter and enabling a low power operation thereof. In addition, in order to update a weight, instead of an analog signal, a probability signal is applied using the above-described analog-stochastic converter, thereby updating a weight in a fully-parallel manner in a synaptic element array having an intersection structure. Accordingly, it is possible to shorten a time for weight update.
