 If you apply the above algorithm to each pixel in the image, the result should look like a blurry, out-of-focus version of the original.
 
-### 5.) Threshold Filter (Black & White)
-- **Flag:** `-t`
-- **Description:** Converts each pixel in the image to pure black or white based on its intensity. If the average of red, green, and blue is greater than or equal to 128, the pixel becomes white (255,255,255); otherwise, it becomes black (0,0,0).
-- **Usage example:**
-```sh
-./filter -t input.bmp output.bmp
-```
-
 ### 6.) Brightness Adjustment Filter
 - **Flag:** `-B <value>`
 - **Description:** Increases or decreases the brightness of the image by adding a fixed value to each pixel's R, G, and B channels. The value should be an integer—positive to increase, negative to decrease.
