Title: Image processing method
Inventor: Archil Tsiskaridze
IPC: G06T19/20
Filed: 2021-05-26
Abstract: The present invention relates to a technique for selectively recovering features of an original surface (e.g. boundary) representation after the original surface representation has been converted to a digitised image, digitally altered, and a new surface representation generated from the digitally altered digitised image. It involves tracking the portions of the digitised image that are digitally altered and/or not digitally altered, and selectively recovering only the portions of the original surface representation that have not been digitally altered. The original surface representation may then be used as a template to recover accuracy and reintroduce detailed features that would otherwise be lost when converting into image space, while maintaining alterations or manipulations intentionally introduced. It comprises a method of manipulating a virtual representation of a three-dimensional object by obtaining a master surface representation of the object, sampling a bounding volume containing the master surface representation to generate a digitised three-dimensional representation of the object. This is then modified to generate a slave surface representation of the object from the modified representation and the slave surface representation is adapted by identifying one or more points in the slave surface representation that are associated with unchanged voxels in the modified digitised three-dimensional representation and transferring each of the identified one or more points in the slave surface representation to a respective location on the master surface representation.

Title: Method and system for generating a financial infographic of a user through a financing platform
Inventor: VINCENT SOH AIK GUAN
IPC: G06Q40/03
Filed: 2021-12-30
Abstract: A computer implemented method of generating a cost of financing and a financial infographic for a loan or investment on a financing or investment platform. The cost of financing is determined by adjusting a base financing rate in response to user-selected risk metrics to produce a risk-adjusted financing rate. The financial infographic comprises the loan or investment applicant’s financing status and the risk-adjusted financing rate (i.e. the cost of financing). The base financing rate may be based on an applicant’s credit score or their financing status, which may include personal banking details, occupation, owned property, business details, or ratings from credit risk agencies. The user-selected risk metrics may be used to determine a risk reduction incentive rate, and the risk-adjusted financing rate (i.e. the cost of financing) may be determined by deducting the risk reduction incentive rate from the base financing rate.
