Title: Selectively applying color to an image
Inventor: QUAN ZHU
IPC: G06T11/60
Filed: 2019-01-11
Abstract: A method, a system, and a computer program product for generating a selective color image. The method includes capturing a color image data within a current scene and retrieving image color values from the color image data. The method further includes receiving a selection of at least one location within the color image data and generating a color mask and applying the color mask to the color image data to generate a color masked image data. The method further includes combining the color masked image data with monochromatic image data of the current scene to create a selective color image that includes the monochromatic image data with the at least one portion, and then providing the selective color image to at least one output device. The mask may be generated by calculating a probability distribution of each pixel of the colour image relative to the selected location and applying a threshold to the distribution to generate the colour mask wherein the colour mask encompasses at least one region, including the selected location, of the image having a probability of matching an average colour that is greater than the threshold value. The image processing may also include generation of a depth map which may be used to identify unmasked regions adjacent to the masked portion with a similar depth and adding said region to the masked area.

IPC: G01N1/22
Filed: 2018-12-19
Abstract: A sample handling system receives a downhole sample. The sample handle system conditions the sample using a separator and filters to allow discharge of unwanted liquids and particulates prior to flowing the sample to one or more analyzers. Separating the moisture and particulates from the sample improves the operation of the components of the sample handling system, for example, by eliminating unwanted condensate or moisture. A coalescing filter, for example, may protect a proportional valve by removing unwanted particulates and liquids from the sample. Additionally, main components of the sample handling system are accessible from a front of a housing to allow for ease of repair and replacement.
