+    **`cv2.imread()` - Read an Image**
+
+    **Purpose:** Load an image from a file and convert it to a NumPy array.
+
+    **Syntax:**
+    ```python
+    image = cv2.imread(filename, flags)
+    ```
+
+    **Common Flags:**
+    - `cv2.IMREAD_COLOR` (default, loads a color image).
+    - `cv2.IMREAD_GRAYSCALE` (loads the image in grayscale).
+    - `cv2.IMREAD_UNCHANGED` (loads the image as is, with alpha transparency if available).
+
+    **Return:**
+    - A NumPy array representing the image.
+    - Returns `None` if the image cannot be loaded.
+
+    **Example:**
+    ```python
+    import cv2
+    image = cv2.imread('image.jpg', cv2.IMREAD_COLOR)
+    ```
+    """)

+    **`cv2.imshow()` - Display an Image**
+
+    **Purpose:** Show an image in a window.
+
+    **Syntax:**
+    ```python
+    cv2.imshow(window_name, image)
+    ```
+
+    **Requirements:**
+    - Call `cv2.waitKey()` to keep the window open until a key is pressed.
+    - Call `cv2.destroyAllWindows()` to close the window(s).
+
+    **Behavior:**
+    - Displays the image in a resizable window.
+    - The image must be a NumPy array.
+
+    **Example:**
+    ```python
+    import cv2
+    cv2.imshow('Image Window', image)
+    cv2.waitKey(0)  # Wait for a key press
+    cv2.destroyAllWindows()  # Close the window

+    **`cv2.imwrite()` - Write/Save an Image**
+
+    **Purpose:** Save an image to a file.
+
+    **Syntax:**
+    ```python
+    cv2.imwrite(filename, image)
+    ```
+
+    **File Format:**  
+    Determined by the file extension (`.jpg`, `.png`, etc.).
+
+    **Return:**  
+    - `True` if the image is saved successfully, `False` otherwise.
+
+    **Optional Parameters:**
+    - **JPEG Quality:** `cv2.IMWRITE_JPEG_QUALITY` (0 to 100, default is 95).
+    - **PNG Compression:** `cv2.IMWRITE_PNG_COMPRESSION` (0 to 9, default is 3).
+
+    **Example:**
+    ```python
+    import cv2
+    cv2.imwrite('output.jpg', image)
