Part 3. JP2 vs. JPG

a. What's the Difference Between JP2 and JPG?

The JP2 file format was an upgrade of JPEG. But several years down the line, the form is not supported in digital cameras with no office application, painting program, or web browser supporting it directly. Many users even prefer the original JPG file format as JP2 has got lots of visual distortion. Though the two do share names, their similarities are almost non-existent.

The format has their specific strengths and weakness. JPG (Joint Photographic Expert Group), came into picture in the year 1986, and is still widely used today. Converting images to jpg is normally accompanied by some loss in quality because of its lossy format. However, the format delivers decent quality and has good ratios when compressed, a feature that has made it gain wide popularity in digital conversions. The format is compatible with almost all devices because it has been present for a long time.

JP2 came into picture 8 years later after JPG and was then considered as the ultimate successor of JPG. The format allows user to make a choice between the mathematical lossy compressions, and the lossy compression, in just a single architecture. JP2 was not however widely implemented as its developers had anticipated. The format was more complicated and required a lot of computational ability to function smoothly. Its speed was therefore very low because computer capability in the early 2000s was still down. Presently, JP2 image format is widely used in satellite images, cinemas, devices used for digital images, scanners, and big devices used for technical images. All is however not lost for the file format as there are still chances for growth and popularity.

b. JP2 Features & JPG Features

JP2 Features

• The architecture for performing conversions, with or without data lose, is the same.
• The format can support huge amount of file sizes, big ranges dynamically, and a number of devices.
• You get to deliver images with different quality or resolution in just one file.
• There is extremely low loss in quality when performing either encoding or decoding, across the different cycles.
• Low chances of error occurrence as the formats is keen with the bits when changing formats.
• Easy to work on specific parts of an image when working when using this format.
• The format supports high compression of files especially when the bitrates are low.

JPG Features

• Performs file size reduction with thin quality degrade signs. This is achieved by JPG’s change of space color feature that makes it possible to separate the chrominance and brightness components.
• Makes it possible to control the amount of size a file can be reduced to.
• Provides coding for DCT to make it lossless.
• Allows the low quality files undergoing encoding be encoded progressively after its byte stream has been decoded partially.

Each of the two file formats is critical in its diverse tasks, with both having their advantages and disadvantages. As mentioned, JPG is popular because of its fast speed and compatibility with many devices used today. JP2, on the other hand, is useful for maintaining high-quality file formats and is therefore used in areas like satellite image and TV contents streaming.
