No, Actually cv2 was a old Interface of old OpenCV versions named as cv. it is the name that openCV developers choose when they created the binding generators.

This Computer Vision tutorial is designed for both beginners and experienced professionals, covering both basic and advanced concepts of computer vision, including Digital Photography, Satellite Image Processing, Pixel Transformation, Color Correction, Padding, Filtering, Object Detection and Recognition, and Image Segmentation.

Example: Suppose we provide audio data of thousands of bird songs. In that case, the computer learns from this data, analyzes each sound, pitch, duration of each note, rhythm, etc., and hence identifies patterns similar to bird songs and generates a model. As a result, this audio recognition model can now accurately detect whether the sound contains a bird song or not for each input sound.

Computer vision is a field of study within artificial intelligence (AI) that focuses on enabling computers to Intercept and extract information from images and videos, in a manner similar to human vision. It involves developing algorithms and techniques to extract meaningful information from visual inputs and make sense of the visual world.

Sony recently introduced two E-mount lenses for its mirrorless camera systems, the Sony E 10-20mm F4 PZ G  with the APS-C sensor coverage and Sony FE PZ 16-35mm F4 G with Full-frame coverage to increase its number of lenses with power zoom to six. 4 of these lenses  are designed to cover APS-C sensors and 2 for Full-Frame. Below is the list of Sony lenses that features power zooms:

Sony latest cine line cameras, FX3 and FX30 features zoom controls on their bodies to remotely control the zoom function of these lenses. The vlogger focused Sony ZV-E10 has one of these physical zoom controls on the body. Besides the consumer cameras, Sony's professional cinema line FX6 and FX9 have large zoom rockers on their bodies too.

Computer vision, a fascinating field at the intersection of computer science and artificial intelligence, which enables computers to analyze images or video data, unlocking a multitude of applications across industries, from autonomous vehicles to facial recognition systems.

OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products.

In a similar fashion to Computer Vision Work, In CV we have a camera to capture the Objects and Then it processes that Visual data by some pattern recognition algorithms and based on that property that object is identified. But, Before giving unknown data to the machine/Algorithm, we trained that machine on a vast amount of Visual labelled data. This labelled data enables the machine to analyze different patterns in all the data points and can relate to those labels.

These are just a few examples of the many ways that computer vision is used today. As the technology continues to develop, we can expect to see even more applications for computer vision in the future.

Power Zoom is a lens feature where you can use the physical controls (usually a rocker switch) on the lens body or camera in order to electronically zoom in and out the lens in a  smooth and controlled way. Without a power zoom, rotating the zoom ring manually with hand generally introduces shake to the footage and it is hard to achieve a constant zooming speed.

OpenCV uses various algorithms, including but not limited to, Haar cascades, SIFT (Scale-Invariant Feature Transform), SURF (Speeded-Up Robust Features), and ORB (Oriented FAST and Rotated BRIEF).

Prerequisite: Before Starting Computer Vision It’s Recommended that you should have a foundational knowledge of Machine Learning, Deep learning and an OpenCV. you can refer to our tutorial page on prerequisites technologies.

Computer Vision Works similarly to our brain and eye work, To get any Information first our eye capture that image and then sends that signal to our brain. Then After, our brain processes that signal data and converted it into meaningful full information about the object then It recognizes/categorises that object based on its properties.
