Ques:- What is 3D vision and how is it different from 2D computer vision?
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.
Ques:- How does occlusion affect stereo matching, and how can it be handled?
Right Answer:
Occlusion affects stereo matching by causing parts of the scene to be hidden from one of the cameras, leading to incorrect depth estimation. It can be handled using techniques like occlusion detection, where algorithms identify occluded regions and either ignore them or use inpainting methods to estimate depth based on visible areas.
Ques:- Explain the concept of depth perception in 3D vision. How is it achieved computationally?
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.
Ques:- How does SLAM (Simultaneous Localization and Mapping) work in 3D vision systems?
Right Answer:
SLAM (Simultaneous Localization and Mapping) in 3D vision systems works by using sensors to gather data about the environment while simultaneously tracking the position of the sensor itself. It creates a map of the surroundings by identifying features in the 3D space, such as points, lines, or surfaces, and updates the sensor's location based on the movement and changes in the environment. This process involves algorithms that fuse data from various sources, like cameras and LiDAR, to ensure accurate mapping and localization in real-time.
Ques:- What are common algorithms used for stereo matching?
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)
Ques:- Add Design, Layout etc.
Right Answer:
To add design and layout, use principles like balance, contrast, alignment, repetition, and proximity. Choose a color scheme, typography, and imagery that align with the brand. Use grids for structure and ensure a clear hierarchy for content.
Ques:- What is the difference between vector and raster graphics?
Right Answer:
Vector graphics are made up of paths defined by mathematical equations, allowing them to be scaled infinitely without losing quality. Raster graphics are composed of pixels, which can lose clarity when resized.

Ques:- My previous company experiences till date
Right Answer:
I have worked at [Company Name] as a graphic designer, where I focused on creating visual content for marketing campaigns. I also collaborated with the team on branding projects and developed user interfaces for websites. My experience includes using tools like Adobe Creative Suite and Sketch to deliver high-quality designs that meet client needs.
Ques:- MY Experience Computer Skills
Right Answer:
I have experience with graphic design software such as Adobe Photoshop, Illustrator, and InDesign. I am skilled in creating visual content, editing images, and designing layouts for print and digital media.
Ques:- What can you give or make changes as a Creative person?
Right Answer:
As a creative person, I can bring fresh ideas, innovative designs, and unique perspectives to projects. I can also adapt existing concepts to improve functionality, aesthetics, and user experience.
Ques:- How can you set a minimum width for IE?
Right Answer:
You can set a minimum width for IE using the `min-width` property in CSS. For better compatibility, you can also use a conditional comment to target IE specifically and apply a fallback using `width` or `min-width` in pixels. For example:

```css
.post-title {
min-width: 300px; /* Standard way */
}

/* For IE 6-8 */
<!--[if lt IE 9]>
<style>
.post-title {
width: 300px; /* Fallback for older IE */
}
</style>
<![endif]-->
```
Ques:- What is alternate Style Sheet? How to link?
Right Answer:
An alternate style sheet is a CSS file that provides different styling options for a webpage, allowing users to switch between styles. To link an alternate style sheet in HTML, use the `<link>` tag with the `rel` attribute set to "alternate stylesheet" and specify the `title` attribute for identification. For example:

```html
<link rel="stylesheet" type="text/css" href="style1.css" title="Style 1">
<link rel="alternate stylesheet" type="text/css" href="style2.css" title="Style 2">
```

Users can then select the alternate style through a user interface or browser settings.
Ques:- Why do style sheets exist?
Right Answer:
Style sheets exist to separate content from presentation, allowing for consistent styling across multiple pages, easier maintenance, and improved loading times.
Ques:- Why does Netscape lose my styles ?
Right Answer:
Netscape may lose styles due to its limited support for CSS standards, improper CSS syntax, or issues with the document structure that prevent styles from being applied correctly.
Ques:- What are the different components of the ARM toolchain
Right Answer:
The different components of the ARM toolchain are:

1. **Compiler** (e.g., ARM GCC)
2. **Assembler** (e.g., ARM Assembler)
3. **Linker** (e.g., ARM Linker)
4. **Debugger** (e.g., ARM Debugger)
5. **Libraries** (e.g., ARM Standard Libraries)
6. **Build Tools** (e.g., Make, CMake)
Ques:- How do you optimize AEM applications for performance and scalability

Ques:- How does RTE ensure data consistency in communication
Right Answer:
RTE ensures data consistency in communication by using a combination of mechanisms such as data versioning, synchronization points, and the use of consistent data types. It manages the timing of data updates and ensures that all components access the most recent and valid data through the use of a reliable communication protocol and by maintaining a consistent state across the system.
Ques:- What are the common types of linking errors and how do you resolve them
Right Answer:
Common types of linking errors include:

1. **Undefined References**: Occurs when a function or variable is declared but not defined. Resolve by ensuring all referenced functions/variables are defined and linked correctly.

2. **Multiple Definitions**: Happens when the same function or variable is defined in multiple files. Resolve by using `extern` for declarations in header files and ensuring only one definition exists.

3. **Library Not Found**: Occurs when the linker cannot find a specified library. Resolve by checking the library path and ensuring the library is correctly installed and linked.

4. **Incompatible Object Files**: Happens when object files are compiled with different settings or incompatible versions. Resolve by recompiling all object files with consistent settings.

5. **Symbol Conflicts**: Occurs when two or more symbols have the same name. Resolve by renaming conflicting symbols or using namespaces.

6. **Incorrect Link Order**: Happens when libraries are linked in the wrong order, causing dependencies to be unresolved
