What are the factors that influence the performance of algorithm?
The performance of an algorithm depends primarily on two concepts: concurrency and number of operations per input unit. Concurrency occurs when an algorithm can split its data into parts and work on each part in parallel, such as a binary sort algorithm that uses "threads" to break its work into equal loads. JPEG algorithms can operate on 8x8 blocks of pixels, and are well-suited to concurrent algorithms, while solving a long algebraic equation may not be suitable for concurrent operation if the results of each step determine the following step. The second factor of performance is known as the Big-O notation. This is summarized as an algorithm's response to the size of the input, where O(1) is fixed time (and fastest), and O(n) is a linear increase to input size, and larger values, such as O(n^2) representing exponential growth of processing time dependent on input size, or O(n!) representing factorial growth (very poor scaling). Other models that represent scaling also exist, but Big-O appears to be one of the most common models for conveying the cost of an algorithm.
Can you retrieve a JPEG file out of a HTML file?
A .jpeg file is not in an HTML file. It is a separate file that is called from the HTML file to display on the browser. You can get the URL of the jpeg file from the HTML file and if the graphic is still there, the file can be obtained from its location. If you are on the actual web page that displays the image, you can usually right click on the image and select 'Save As' and save the file. Some web sites have their images protected to prevent you from saving their photos onto your harddrive.
How do you convert image file to byte code in asp with example code?
How to convert bytecode to .jpeg file in servlet? Thanks
An example of paint application document?
Paint application documents can be saved in Jpeg or Gif formats. You can design logos, pictures or diagrams in Paint.
What is the difference between a jpg image and a saved-for-web jpg?
A jpg or jpeg file is a jpeg file is a jpeg file. It is an image file that can be used anywhere including websites. The only difference might be the actual size and therefore quality of the image in question. When you want to put an image online you want to make it small and efficient and therefore easier and faster to download when someone views it online. We take pictures all the time and the file size of these images can typically be HUGE. We don't need all the data stored in the file when placing it on a screen image so we save it in a smaller format when we need to.
What is the difference between a JPEG and a JPEG2000?
JPEG2000 is a newer version of the JPEG encoding algorithm.
Do JPEG images lose minor image details?
Generally yes, the JPEG algorithm uses a lossy compression, so minor image details are lost. For more details about the JPEG algorithm visit the related link.
If you convert Bitmap to JPEG does this make the picture better for printing?
No. JPEG uses a compression algorithm with Loss (it means that the new picture's quality is worse than the original's) The picture in JPEG takes less place on the storage device, but it has some artifacts because of the compression. Nowadays a good JPEG compression is invisible to the eye, but you can't have a better quality for printing.
How many bytes will a JPEG screen image be?
The size of a JPEG file depends on the compression algorithm and on the content of the source image. There is no direct answer to you question. What you can do to find it out is to capture the screen, then use mspaint to save the file as a bitmap and after that convert the bitmap to a jpeg using an image converter that allows you to play with the jpeg parameters - for example AZImage. See also related questions and links.
What are the different types of coding techniques?
Types of testing is broadly classified as Black box testing and white box testing
How large can a 2.37MB JPEG file be enlarged?
There is no upper limit when enlarging an image. The limiting factor is the quality loss. When enlarging you will always loose quality. Note: the filesize for a JPEG does not tell much about it since JPEG uses a lossy compression algorithm - i.e. the resulting file size is depending a lot on the original image and the compression level.
How do you upload your photo to my poke card.com?
You have to click the picture where you put it usually on desktop then click where it shows file click save as then click jpeg not jpeg 2000.
What do file formats determine about graphics?
There are about 30+ formats, but lets focus on jpeg, bmp, & png. I'll go from worst to best. jpeg is not good for graphics at all. Ever the highest quality jpeg brings noise and sometimes blur to your graphic. (highly not recommended for graphics.) bmp or bitmap is good for graphics, no blur or noise. It's clear down to the pixel. The problem with bmp is that the coding is very long. 2 - 70+ times larger of a file compared to a jpeg. (Not really recommending this for graphics.) png or Portable Network Graphics is the ideal file format for graphics. png is as high of quality as bmp, but it can even have transparency in it. Transparency is needed for mostly all graphics. Also png is half to a third less coding than jpeg format. (Highly recommended for graphics.)
Image files that are repeatedly compressed by the JPEG algorithm suffer visible quality degradation?
There are some opinions that this is the case (see the link "JPEG Image Compression Degradation"), but I cannot agree. Normally there is no major degradation of the image by repeating the open/save jpeg operation again and again. The reason is the after the first compression step, the image colors are shifted to improve the jpeg image. After the second open the colors are already very close to the jpeg compressed data and there will be no significant change anymore. There are minimal differences, but this is it. Even with 5% quality, the output image quality remains stable. The file size remains also stable.
What is an animated JPEG?
Animated JPEG are multiple single jpeg images that is runned under a javascript which runs the jpeg like a animated GIF, by frames of each images.
How many form of j-peg are there?
JPEG is a definition of an image compression algorithm. Any image can be compressed using any combination of compression methods, both lossy and lossless, or a combination of both. The only real requirement for a JPEG image is that any file compressed as a JPEG must be in a format that can be read and expanded by any JPEG-supported device. JPEG is an acronym of Joint Photographic Experts Group which defines the standard. Although there is just one standard, which originated in 1992, it has been revised through the years to incorporate extensions. There are currently two primary extensions: Exif (Exchangeable Image File format) and JFIF (JPEG File Interchange Format), which largely describe how the embedded JPEG image is transported between devices. The JPEG extensions also allow multiple images to be embedded in a single file. The JPEG compression algorithm itself is a lossy algorithm which allows a degree of variability, providing a trade-off between image quality and file size. Typically, an image can be reduced to around 1/10th of its original size (10:1 compression) with little perceptible loss in quality. However, while JPEG includes a lossless mode, few products actively support it. For lossless compression, TIFF, GIF, PNG and RAW formats are the most commonly supported. The RAW format is the best format for lossless digital cameras as this captures an exact binary dump of the video chip, thus allowing image editors and post-processors to reveal data that would otherwise be lost (such as detail within shadows). Once edited, the RAW image can be compressed to JPEG or other lossy format for transport purposes. JPEG files typically have a .jpg file extension, although .jpeg, .jpe, .jfif and .jif are common alternatives for extended mode JPEG. However, the file extension is merely a hint to the file's content, nothing more, and are largely used to associate files with programs. The actual content is defined within the file's own metadata (the file header). Thus image decoders use the metadata to physically decode the file, never the file extension. JPEG can also be embedded into other formats. For instance, TIFF files often use JPEG encoding to incorporate a thumbnail of the image within the file's metadata.
What does the jpeg stand for?
