What are Computer Vision tests?

Dive into our Computer Vision suite to assess and polish your expertise in one of tech’s hottest fields. Designed to reflect the latest industry demands, these tests are tailored to examine your proficiency in core areas like image recognition, algorithm understanding, and data interpretation. Employers value these metrics as they often correlate with job performance in roles that require such technical finesse. To excel, familiarize yourself with machine learning principles, object detection, and computational photography among others. These are key competencies that companies look for, and our tests provide a comprehensive canvas to demonstrate your skills.

Why do employers use Computer Vision tests?

In today’s data-driven landscape, employers in tech and product development heavily rely on Computer Vision experts. The ability to automate tasks that require visual cognition is vital for numerous applications, from autonomous vehicles to facial recognition software. Hence, they utilize these specialized tests to identify candidates who are not only adept at coding but also possess a deep understanding custom-tailored to this niche. Successfully navigating these tests reflects a candidate’s readiness to handle complex visual data and contribute to cutting-edge projects.

How do Computer Vision tests work?

When you’re presented with a Computer Vision test during the hiring process, expect a mixed bag of multiple-choice questions and practical tasks. The duration varies, but each question is typically timed, encouraging precision under pressure. To prepare, balance speed with accuracy, and get comfortable with nuance in visual data and pattern recognition. Understanding theoretical concepts is just as crucial as being able to apply them, so make sure you’re well-rounded in both aspects.

What skills do Computer Vision tests cover?

Tackling our Computer Vision tests requires a solid grasp of algorithm development, especially as it pertains to real-world visual data processing. Brush up on your knowledge of image segmentation, edge detection, and 3D reconstruction. These tests are designed to gauge your familiarity with both the theoretical underpinnings and practical implementations of computer vision algorithms, so an interdisciplinary approach is key. Think of these skills as your toolkit in solving the visual puzzles you will face.

Score: /6

In the context of Computer Vision, which of the following convolutional neural network (CNN) architectures introduced the concept of 'inception modules' that perform convolutional operations with multiple kernel sizes in parallel?

LeNet-5
AlexNet
GoogLeNet/Inception
ResNet
VGGNet

Given an RGB image matrix, what is the correct sequence of dimensions when reshaping the matrix into a flat array for a neural network input layer?

(height * width, channels)
(channels, height * width)
(height, width * channels)
(height * width * channels,)

How does max pooling in a convolutional neural network affect the input feature map?

It increases the dimensionality of the feature map.
It keeps the dimensionality of the feature map the same.
It reduces the dimensionality of the feature map and retains the most significant information.
It eliminates the spatial hierarchies in the input feature map.

In the context of computer vision and image processing, feature scaling is applied to ensure that:

Image contrast is enhanced by spreading out the most frequent intensity values.
Image data has a mean of zero and a standard deviation of one.
Input features have equal contribution to the distance metrics when calculating similarities.
All pixels of an image are sieved through a filter to detect edges.
Images of different sizes can be concatenated to form a larger batch for processing.

Which of the following methods is considered a non-linear dimensionality reduction technique useful in computer vision?

Principal Component Analysis (PCA)
Linear Discriminant Analysis (LDA)
t-Distributed Stochastic Neighbor Embedding (t-SNE)
Matrix Factorization

In image segmentation tasks, which algorithm is particularly known for its use in dividing an image into regions based on intensity discontinuities?

K-Means Clustering
Region Growing
Edge Detection
Watershed Algorithm
Histogram Equalization
