Disclosed is a distortion rectification method, comprising: taking a wide-angle photograph using a camera of a terminal; determining distortion regions and non-distortion regions in the wide-angle photograph; obtaining a target distortion region selected by a user; dividing the target distortion region into M grid regions of a first pre-set size, wherein M is an integer greater than or equal to one; and respectively performing distortion rectification on the M grid regions of the first pre-set size. Also disclosed is a terminal.

The present invention provides an auxiliary berthing method and system for a vessel. In the berthing method, by a solar blind ultraviolet imaging method, a position and an attitude of a vessel relative to a shoreline of a port berth during berthing are calculated by at least two solar blind ultraviolet imaging modules according to light signals received by a solar blind ultraviolet light source array arranged in advance on the shore. Further, when more than three solar blind ultraviolet imaging modules are used, in the method and device of the present invention, a normalized correlation algorithm and a data fusion algorithm are used to improve the accuracy of the position and attitude data of the vessel.

A material data collection system allows capturing of material data. For example, the material data collection system may include digital image data for materials. The material data collection system may ensure that captured digital image data is properly aligned, so that material data may be easily recalled for later use, while maintaining the proper alignment for the captured digital image. The material data collection system may include using a capture guide, to provide cues on how to orient a mobile device used with the material data collection system.

A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. The system swaps garments in a digital asset to garments that are designed using the system. The wear pattern is created by a laser using a laser input file. Generating the preview image comprises combining first and second contributions to obtain a combined value for a pixel at the pixel location of the preview image.

In one embodiment, the system may determine an estimated distance of an eye of a user to a display plane of a display. The system may access, from a memory storage, a number of transmission maps characterizing non-uniform transmission characters of the display as measured from a number of pre-determined view positions within a measurement plane. The measurement plane may be separated from the display plane by a known distance. The system may generate a custom transmission map for the estimated distance of the eye based on the transmission maps using light field rendering. The system may determine a custom correction map based on the custom transmission map. The system may adjust an image to be displayed on the display using the custom correction map. The system may display the image adjusted using the custom correction map on the display.

An information processing apparatus configured to paste a full-spherical panoramic image along an inner wall of a virtual three-dimensional sphere; calculate an arrangement position for arranging a planar image closer to a center point of the virtual three-dimensional sphere than the inner wall, in such an orientation that a line-of-sight direction from the center point to the inner wall and a perpendicular line of the planar image are parallel to each other, the planar image being obtained by pasting an embedding image to be embedded in the full-spherical panoramic image, on a two-dimensional plane; and display a display image on a display unit. The display image is a two-dimensional image viewed from the center point in the line-of-sight direction in a state in which the full-spherical panoramic image is pasted along the inner wall of the virtual three-dimensional sphere and the planar image is arranged at an arrangement position.

Methods and systems for training a neural network include generate an image of a mask. A copy of an image is generated from an original set of training data. The copy is altered to add the image of a mask to a face detected within the copy. An augmented set of training data is generated that includes the original set of training data and the altered copy. A neural network model is trained to recognize masked faces using the augmented set of training data.

Described are systems and processes for generating multi-view interactive digital media representations (MIDMR) for display on a user device. In one aspect, a mobile device is provided which comprises a display, one or more processors, memory, and one or more programs stored in memory. The one or more programs comprise instructions for locking the mobile device, and providing a lock screen on the display in a lock mode upon receiving user input for accessing the mobile device. The lock screen may display a dynamic MIDMR that dynamically changes without user input, which provides an interactive three-dimensional representation of an object that is responsive to user interaction with the mobile device. The dynamic MIDMR displayed is selected based on predetermined criteria, and may change based on a predetermined algorithm that includes weighted predetermined criteria factors as variables and recalculates the algorithm value to determine changes to the dynamic MIDMR.

Certain aspects of the technology disclosed herein involve combining images to generate a wide view image of a surrounding environment. Images can be recorded using an stand-alone imaging device having wide angle lenses and/or normal lenses. Images from the imaging device can be combined using methods described herein. In an embodiment, a pixel correspondence between a first image and a second image can be determined, based on a corresponding overlap area associated with the first image and the second image. Corresponding pixels in the corresponding overlap area associated with the first image and the second image can be merged based on a weight assigned to each of the corresponding pixels.
