Version 0.20.0 of Windows 10 PowerToys adds a new utility to its set of featured applications. The Color Picker allows you to quickly find the specific and unique identifying information for any color displayed on your computer screen. That information is copied to your Windows 10 clipboard where it can be retrieved later.

For developers, graphic artists, photographers, marketers, and many others, knowing the precise identification information for a particular color is vital. For consumers, blue is blue, but for the creators and developers there are thousands of shades of blue. Color Picker allows these creators a simple way to consistently use the right shade of blue.

This how-to tutorial shows you how to activate and use the Color Picker utility found in the latest version of Windows 10 PowerToys.

Windows 10 PowerToys: How to activate and use Color Picker

The first step is to download the latest version of Windows 10 PowerToys from the GitHub release page. On the date of this writing, the current release is Version 0.20.0. Color Picker was added to the Windows 10 PowerToys project by Martin Chrzan.

With version 0.20.0 installed and running, open the Windows 10 PowerToys Settings menu and select Color Picker from the left-hand navigation bar. As shown in Figure A, click the Enable Color Picker button to the On position.

Note that the default keyboard shortcut used to activate Color Picker is Windows Key+Shift+C. This key combination can be changed if you wish. Also note that the default setting is to record a color’s identification information in the hexadecimal (HEX) format. You can use the dropdown to change to the RGB setting.

With Color Picker now active, you may close the Windows 10 PowerToys Settings screen.

Perhaps the most powerful aspect of Color Picker is the fact that is a system-wide application. The keyboard combination shortcut of Win+Shift+C will activate Color Picker regardless of what other application(s) are running. Just hover the resulting mouse cursor (Figure B) over the color you wish to record identifying information for and left click your mouse.

The color identifying information will be copied to the Windows 10 clipboard in the form you selected in the Settings. The default setting is HEX.

To zoom in for a more detailed view of the pixels on your screen, use the scroll button of your mouse.

Once the information is stored on your Windows 10 clipboard, you may paste the identification information into the color palette of your preferred editing tool.

Before Windows 10 PowerToys Color Picker, such a seemingly simple operation would have required more than a few applications and some gymnastics with open screens to accomplish. The Color Picker tool greatly simplifies this process and will save developers and creators time when working with color and color design projects.

Vi Weekend Data Rollover Offer Extended Till April 17: All the Details

vi vodafone idea logo image gadgets 360 1600074342843

Vi (Vodafone Idea) has extended its weekend data rollover offer till April 17 from its previous end date of January 17. The company started the data rollover system back in October last year for its prepaid customers and it allows them to carry forward their daily unused data to the weekend. The updated time frame can be spotted in the terms and conditions section on the official Vi website. The weekend data rollover offer is still available with the same plans as before.

Vi website has been updated to show that this promotional offer is applicable from October 19 2020 to April 17 2021. This gives users another three months to enjoy the benefits of weekend data rollover as the offer was initially supposed to end on January 17. The minimum recharge value to avail this offer is Rs. 249 and is valid for unlimited packs with daily data. It is valid for Rs. 249, Rs. 299, Rs. 399, Rs. 449, Rs. 595, Rs. 599, Rs. 699, Rs. 795, and Rs. 2,595 plans. Currently, all these plans are listed on the website with weekend rollover along with an additional offer such as double data, 5GB extra data, or one year subscription to Zee5.

Every plan offered by Vi comes with some amount of data limit, that may not always be completely used. This results in some data being wasted as it resets the next day. With the weekend rollover system, Vi customers will be able to make use of whatever data is unused throughout the week, over the weekend.

Customers should note that unused data between Monday 0000 hours to Friday 2400 hours will be accumulated and made available between Saturday 0000 hours and Sunday 2400 hours. Post that, any and all unused data will be forfeited. The terms and conditions also state that Vi reserves the right to discontinue, modify, or withdraw the roll over or other product features subject to Telecom Regulatory Authority of India (TRAI) regulations.

GeoSim: Photorealistic Image Simulation with Geometry-Aware Composition

WIRELESS kimi lee M3RVFbqKGu4 unsplash 705x470 1

Humans can synthesize unperceived events in their heads, for instance, to imagine how an empty street would look during rush hour. The similar capability of computers may be useful in film making or augmented reality.

A recent paper proposes GeoSim, a realistic image manipulation framework that inserts dynamic objects into existing videos.

This method uses the data captured by self-driving cars to build a 3D assets bank. Then 3D scene layout from LiDAR readings and 3D maps is used to add vehicles in plausible locations. The Intelligent Driver Model is used so that the new objects have realistic interactions with existing ones and respect the flow of traffic. Neural networks are employed to seamlessly insert an object by filling holes, adjusting color inconsistencies, and removing sharp boundaries. It is the first approach to fully consider physical realism and outperforms prior research by qualitative and quantitative measures.

Scalable sensor simulation is an important yet challenging open problem for safety-critical domains such as self-driving. Current work in image simulation either fail to be photorealistic or do not model the 3D environment and the dynamic objects within, losing high-level control and physical realism. In this paper, we present GeoSim, a geometry-aware image composition process that synthesizes novel urban driving scenes by augmenting existing images with dynamic objects extracted from other scenes and rendered at novel poses. Towards this goal, we first build a diverse bank of 3D objects with both realistic geometry and appearance from sensor data. During simulation, we perform a novel geometry-aware simulation-by-composition procedure which 1) proposes plausible and realistic object placements into a given scene, 2) renders novel views of dynamic objects from the asset bank, and 3) composes and blends the rendered image segments. The resulting synthetic images are photorealistic, traffic-aware, and geometrically consistent, allowing image simulation to scale to complex use cases. We demonstrate two such important applications: long-range realistic video simulation across multiple camera sensors, and synthetic data generation for data augmentation on downstream segmentation tasks.
