+# Bitwise Operations
+
+Bitwise operations are operations that are performed on the binary representation of a number. They are very useful for
+combining images, using masks, and more.
+
+There are two most common bitwise operations: `and` and `not`. 
+
+There is also `or` and `xor`, but I have yet to find a use for these, so I will not be covering them. You can google them if you want to learn more.
+
+## And
+
+The `and` operation is used to combine two images. This allows us to use masks to only show certain parts of an image.
+A common use is to have a mask (say one provided by the `inRange` method) and use it to only show the parts of the image
+where the mask is white.
+
+```java
+Core.bitwise_and(Mat src1, Mat src2, Mat dst)
+```
+
+## Not
+
+The `not` operation is used to invert an image.
+
+```java
+Core.bitwise_not(Mat src, Mat dst)
+```

+# Common Methods
+
+While we can't go over every single method in OpenCV, we will briefly go over some of the more common methods that will
+depend on what you are trying to accomplish.
+
+We are always adding more methods to this page, but if you don't see a method you need, you can always google it.
+
+## Mean value
+```java
+Core.mean(Mat mat)
+```
+
+Find the mean value of an image.
+
+**Parameters:**
+- `mat`: The image to find the mean value of.
+
+**Returns:** A `Scalar` object containing the mean value of the image, seperated by channel.
+
+**Example:**
+```java
+Scalar mean = Core.mean(input);
+
+mean.val[0]; // Mean value of the first channel
+mean.val[1]; // Mean value of the second channel
+mean.val[2]; // Mean value of the third channel
+```
+
+## In Range
+```java
+Core.inRange(Mat src, Scalar lowerBound, Scalar upperBound, Mat dst)
+```
+
+Get a binary image of the pixels in a certain range. If the pixel is in the range, it will be white, otherwise it will be black.
+
+**Parameters:**
+- `src`: The image to find the mean value of.
+- `lowerBound`: The lower bound of the range.
+- `upperBound`: The upper bound of the range.
+- `dst`: The output image.
+
+**Returns:** None
+
+**Example:**
+```java
+Scalar lowerBound = new Scalar(0, 0, 0);
+Scalar upperBound = new Scalar(255, 255, 255);
+Mat dst = new Mat();
+
+Core.inRange(input, lowerBound, upperBound, dst);
+```
+
+## Split
+```java
+Core.split(Mat src, List<Mat> dst)
+```
+
+Split an image into its channels.
+
+**Parameters:**
+- `src`: The image to split.
+- `dst`: The list of images to store the channels in.
+
+**Returns:** None
+
+**Example:**
+```java
+ArrayList<Mat> channels = new ArrayList<>();
+Core.split(input, channels);
+```
