## Blog # How To Do a Pixel Interpolation

Video pixel manipulation with the help of pixel Interpolation is one technique to ease the graphic artist’s job. It can be done by taking a still photograph and then cropping it to reduce its size. Then the original image can be downsampled to fill up the extra space, and the final result would be a lower resolution image. The final result’s quality depends on how good the pixel mapping of the original source image is.

Media restoration companies, like Media Medic, can perform pixel operation on a series of chosen image pixels. We need to convert the image pixels to screen pixels and then multiply them with the screen ratio for the final result. The technique is known as transform masking. To achieve the best results, transform masking needs to be performed on many images rather than on just one picture so that the effect can be uniform across the screen.

A pixel lookup is a method used to determine a point’s location in the source image using the pixel units for calculating distance. There are many uses of pixel units. For example, the Pixels per inch or Pixels per millimeter are used for measuring devices such as cameras.

Some systems use a different unit of measurement, such as pixels per meter. Some systems consider the source image resolution for calculating the pixel coordinates.

There are several uses of the pixel lookup, and it can be used for calculating the distance between two points on the screen. The resulting value is always closest to the position of the point on the screen. The other uses are calculating the displacement of a point from the current location, and it also can be used to calculate the translation of a point based on the coordinates given. The other important function of the pixel lookup is it can be used to extract the color from a source image.

A pixel lookup works by first finding the location of the point within the image. Then the next important step is to get the pixel value of the point within the image. It is done by the use of the x coordinate and the y coordinate for the first-pixel value. If the coordinates are negative, the result will be a zero. The next step is to get the color of the point using the color function designed for mathematical operation. This is different from the normal function, which uses the normal color of a point.

For calculating the color of a point, first find the origin point, then find the target point and place the cursor on the destination point. The mouse movement should be aimed at the center of the target point and when you have finished pointing, the mouse should be released. The mouse should be clicked to lock the current coordinates. You can also use the ‘escape’ key to jump to the next frame.

If you want to know the pixels that are located outside the range of a point, you need to add a second coordinate after the current point. For this, change the current coordinates to the origin point of the second coordinate. Then place your cursor on the destination point and use the mouse to click. The resulting numbers indicate the pixels that are located beyond the range of the current point. These are called ‘outside pixels’, and you should calculate their average size before getting them as the computed value.

This is just one way of doing a pixel lookup. It uses some special software and mathematical functions for computing the sums. It is quite similar to the mathematical summation operator in computers. Some other useful functions for knowing the pixels and the origin’s distances are the sin, cos, tan, and the distance formula. Start An Audio Cleanup Project
