Right Answer:
3D vision refers to the ability of a system to perceive depth and spatial relationships in a three-dimensional space, allowing it to understand the shape, size, and position of objects. In contrast, 2D computer vision processes images as flat, two-dimensional representations, lacking depth information.

Right Answer:
Common algorithms used for stereo matching include:

1. Block Matching
2. Semi-Global Matching (SGM)
3. Dynamic Programming
4. Graph Cuts
5. Belief Propagation
6. Deep Learning-based methods (e.g., Convolutional Neural Networks)

Right Answer:
A point cloud is a collection of data points in a three-dimensional coordinate system, representing the external surface of an object or environment. It is generated using 3D scanning technologies, such as LiDAR, photogrammetry, or depth sensors. In 3D vision applications, point clouds are used for object recognition, scene reconstruction, and analysis in fields like robotics, computer vision, and virtual reality.

Right Answer:
Depth perception in 3D vision refers to the ability to perceive the distance of objects in a three-dimensional space. It is achieved computationally through various techniques, including:

1. **Binocular Disparity**: Using two slightly different images from each eye to calculate depth based on the difference in their positions.
2. **Monocular Cues**: Utilizing single-eye cues like size, texture gradient, overlap, and perspective to infer depth.
3. **Motion Parallax**: Observing how objects move relative to each other as the observer moves, providing depth information based on their relative motion.
4. **Depth Sensors**: Using devices like LiDAR or stereo cameras to measure distances directly.

These methods help create a perception of depth in 3D environments.

Right Answer:
Stereo cameras work by capturing two images simultaneously from slightly different angles, similar to how human eyes perceive depth. By comparing the two images, the system calculates the disparity between corresponding points, allowing it to determine the distance of objects in the scene and create a 3D representation.

Right Answer:

To create and manage Components in Adobe XD, follow these steps:

1. **Create a Component**: Select the elements you want to include, right-click, and choose "Make Component" or use the shortcut (Cmd/Ctrl + K).
2. **Edit a Component**: Double-click the component to edit its properties. Changes will reflect in all instances.
3. **Manage Components**: Open the Assets panel (Cmd/Ctrl + Shift + Y) to view and organize your components. You can rename, delete, or drag them into your design.
4. **Override Properties**: Select an instance of a component to override text, colors, or images without affecting the master component.
5. **Detach an Instance**: Right-click on an instance and select "Detach from Component" to convert it back to a regular group.

Use these steps to efficiently create and manage components in your designs.

Right Answer:

The benefit of using Component States in your design system is that it allows you to create variations of a component (like hover, active, or disabled states) within a single component, making it easier to manage and maintain consistency in design while improving efficiency in prototyping and user interaction.

Right Answer:

Adobe XD can export assets in formats such as PNG, JPG, SVG, and PDF. To deliver assets for development, you can use the "Share" feature to create a design spec link or export the assets directly and provide them in a zip file.

Right Answer:

To prototype interactions and transitions in Adobe XD, select the artboard you want to link from, then use the "Prototype" tab. Click on the element you want to make interactive, drag the blue arrow to the target artboard, and set the trigger (like "Tap") and the transition type (like "Slide" or "Dissolve") in the properties panel. Finally, click the play button to preview the prototype.

Right Answer:

Yes, Adobe XD can be used for both web and mobile app design. To handle adaptive layouts, you can use responsive resize features, create artboards for different screen sizes, and utilize components and constraints to ensure designs adjust appropriately across various devices.

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

Right Answer:
* **Epic:** A large, high-level user story that is too big to complete in a single iteration. It's usually broken down into smaller user stories.
* **User Story:** A small, self-contained requirement that represents a valuable piece of functionality for the end-user. It follows the format: "As a [user type], I want [goal] so that [benefit]".
* **Task:** A small, actionable item that needs to be done to complete a user story. It's a technical breakdown of the work required by the development team.

Right Answer:
* **Clear Sprint Goals:** Define specific, measurable, achievable, relevant, and time-bound (SMART) goals for each iteration.
* **Daily Stand-ups:** Facilitate short, focused daily meetings to identify roadblocks and coordinate efforts.
* **Sprint Backlog Management:** Keep the sprint backlog refined, prioritized, and realistic based on team capacity.
* **Timeboxing:** Adhere to time limits for meetings and tasks to prevent scope creep and maintain momentum.
* **Focus on Value:** Prioritize tasks that deliver the most business value within the iteration.
* **Remove Impediments:** Proactively identify and resolve obstacles that hinder the team's progress.
* **Limit Work in Progress (WIP):** Encourage the team to focus on completing tasks before starting new ones.
* **Continuous Feedback:** Regularly review progress, gather feedback, and adapt plans as needed.
* **Defined "Definition of Done":** Ensure a clear understanding of what it means for a task to be considered complete.
* **Team Collaboration & Communication:** Foster open and effective communication and collaboration within the team.

Right Answer:
I've used tools like Jira, Azure DevOps, and Trello for Agile project management. I choose them based on project needs; Jira for complex workflows and robust reporting, Azure DevOps for integrated development environments, and Trello for simpler, visually-oriented task management.

Right Answer:
A product backlog is a prioritized list of features, bug fixes, tasks, and requirements needed to build a product. It's managed through regular refinement, prioritization, estimation, and updates based on feedback and changing business needs, often facilitated by the Product Owner.

Right Answer:
An API Gateway acts as a single entry point for clients to access multiple microservices, handling requests, routing them to the appropriate services, managing authentication, rate limiting, and aggregating responses.

Right Answer:
An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs work by sending requests from one application to another, which then processes the request and sends back a response.

Right Answer:
OAuth is an open standard for access delegation commonly used for token-based authentication and authorization. It allows third-party applications to access a user's resources without sharing their credentials.

In API authentication, OAuth works by having the user authorize the application to access their data. The process involves:

1. The user is redirected to an authorization server to log in and grant permission.
2. The authorization server issues an access token to the application.
3. The application uses this access token to make API requests on behalf of the user.
4. The API validates the token and grants access to the requested resources.

Right Answer:
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods and is typically more lightweight and easier to use, while SOAP (Simple Object Access Protocol) is a protocol that relies on XML for message format and has strict standards for security and transactions. REST is generally more flexible and faster, while SOAP is more suited for enterprise-level services requiring high security and reliability.

Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.
