Abstract: An image segmentation method according to an embodiment of the present invention is performed in a computing device having one or more processors and memory for storing one or more programs executed by means of the one or more processors, and includes the steps of: (a) receiving the input of an image; (b) generating a first-generation image segment set by dividing the input image in an overlapped manner; and (c) generating a second or higher-generation image segment set from the first-generation image segment set, wherein a subsequent-generation image segment set is generated by dividing in an overlapped manner at least one of a plurality of image segments included in the previous-generation image segment set.

Abstract: A wafer to wafer bonding method includes performing a plasma process on a bonding surface of a first wafer, pressurizing the first wafer after performing the plasma process on the bonding surface of the first wafer, and bonding the first wafer to a second wafer. The plasma process has different plasma densities along a circumferential direction about a center of the first wafer. A middle portion of the first wafer protrudes after pressurizing the first wafer. The first wafer is bonded to the second wafer by gradually joining the first wafer to the second wafer from the middle portion of the first wafer to a peripheral region of the first wafer.

Abstract: An operating method of a memory controller, configured to control a non-volatile memory device that performs a refresh read operation, detects a power on state or power off state of the non-volatile memory device and issues a refresh read command. The non-volatile memory device that receives the refresh read command is controlled to perform, one time, the refresh read operation including a read operation on one of a plurality of word lines with respect to each of the plurality of memory blocks.

Abstract: A method of operating a storage device including first and second memory regions includes adjusting a write ratio of the first memory region to the second memory region for write data received from a host in response to a write request from the host, and writing the write data to the first and second memory regions at the adjusted write ratio. The first memory region includes memory cells having a first write speed, and the second memory region includes memory cells having a second write speed that is different from the first write speed.

Abstract: A method of providing special functions includes receiving from a host a first normal command and a first address, and identifying a first special function based on the first normal command and the first address when the first address is in an address range established for special functions according to a predefined rule.
