#What is Computer Vision Tasks?

 A. Single Object Tasks

These tasks assume only ONE main object in the image.

1. Image Classification

The model identifies what the object is.

  • Input: image with a single object
  • Output: the label (name/object category)

Example:
Image → 🐶
Output → “Dog”

There is no location information, only the category.

2. Classification + Localization

The model identifies what the object is AND where it is located.

  • It gives two outputs:
    1. The category (e.g., “Dog”)
    2. The bounding box (the rectangle around the object)

Example:
Image → 🐶 in a garden
Output → “Dog at these coordinates (x,y,w,h)”

This still assumes one main object, but also marks its position.

 B. Multiple Object Tasks

In these tasks, the image contains many objects of different types, and the model must identify each one separately.

3. Object Detection

Detects all objects in the image and draws a bounding box around each of them.

  • Output:
    • Object class (what it is)
    • Bounding box (where it is)

Example:
Image → road scene
Output → “Car”, “Person”, “Traffic light”, each with its own box.

However, object detection doesn’t understand object shape, only boxes.

4. Instance Segmentation

Detects and outlines each object pixel-by-pixel, not just a box.

  • It is more detailed than object detection.
  • Also distinguishes different instances of the same object.

Example:
If there are 3 people:

  • Instance segmentation gives three separate masks (shape outlines)

  • Not just three boxes

This is used in self-driving cars, medical imaging, AR, etc.

Summary Table

Category Task Purpose Output
Single Object Classification What is it? Label only
Single Object Classification + Localization What & Where? Label + box
Multiple Objects Object Detection What & Where (for ALL) Labels + boxes
Multiple Objects Instance Segmentation Exact shape & positionLabels + pixel-level masks


#What is an Image?

An image is made of tiny dots called pixels.
When millions of these pixels are combined together, they form a picture.

Just like:
📍 Brick → wall
📍 Pixel → image

 1. Pixel

Term     Meaning
Pixel (Picture Element)         The smallest unit of an image
Each pixel stores Color information                        
Many pixels together form The whole image


➡️ If you zoom into a photo a lot, you will start seeing little squares — those are pixels.

2. Resolution

Resolution means how many pixels are in an image (its size).

Example:

  • 1920 × 1080 → Full HD 
    • width: 1920 pixels
    • height: 1080 pixels
    • total pixels = 1920 × 1080 ≈ 2 million (2 megapixels)

Resolution Meaning Quality
Low (e.g., 640×480) Fewer pixels Blurry
Medium (e.g., 1280×720) More pixels           Clearer       
High (e.g., 1920×1080) Even more pixels Very clear


So, higher resolution = more pixels = more detail = better quality.

3. Pixel Value

A pixel value says what color that pixel is.

There are two types:

🔹 Greyscale Image (Black & White)

Each pixel has one value → brightness
Range: 0 to 255

  • 0 = Black 
  • 255 = White
  • between = shades of grey

Example:

Pixel Value Appearance
0 Black
128 Grey
255White

🔹 Color Image (RGB)

Color images use three values per pixel:

  • R = Red
  • G = Green
  • B = Blue

Each value ranges from 0 to 255
Combination of these three gives any color.

Example:

       R             G            B            Color       
255 0 0 Red
0 255 0 Green
0 0 255 Blue
255 255 255 White
0 0 0 Black
     255            255            0      Yellow


Quick Summary

Term Definition Example
Pixel Smallest part of an image Dot
Resolution Number of pixels in width × height 1920×1080
Pixel Value Color/brightness of each pixel0–255
