Image data transmitting method

Abstract

The invention discloses an image data transmission method, which is applied in an image data transmission system. Before executing the image data transmission task, the image data transmission system first determines the transmission strategy for the next step through calculation, and if the transmission efficiency of sequentially transmitting subfields is high, then The subfields are transmitted sequentially, and the minimum envelope field is transmitted if the transmission efficiency of the minimum envelope field is high, so as to realize the dynamic decision to sequentially transmit the subfields or the minimum envelope field, and achieve the purpose of improving the overall transmission efficiency of the image data transmission system.

Description

technical field [0001] The invention relates to computer image processing technology, in particular to an image data transmission method. Background technique [0002] Usually, the storage space of the image information on the computer is called the storage domain of the image, which means a logically continuous section of storage space, in which each storage unit stores the characteristic data of a corresponding pixel, hereinafter referred to as The storage domain of an image is simply called a domain. Commonly, a collection of some connected pixels in an image is called an image sub-block, and the sub-block has various shapes, the most common being a rectangle. The storage domain of the image sub-block is located in a logically continuous space of the image domain. Hereinafter, the storage domain of the image sub-block is referred to as sub-domain for short. The set of connected pixels that can envelop a certain or several image sub-blocks is called the envelope block of...

Problems solved by technology

If the existing technology 2 is adopted, the total data volume S sum2 =S(X 1 +X 2 +X 3 +X 4 +X 5 ), the number of transmissions is 5 times; if the existing technology 3 is adopted, the total data volume S sum3 =S(P), the number of transmissions is 1, by S(X 1 +X 2 +X 3 +X 4 +X 5 ) is much smaller than S(P) Knowing that the prior art 3 transmits a large amount of useless data, the transmission efficiency of the prior art 3 is obviously lower than that of the prior art 2 at this time, but due to the rigid setting of the transmission method by the transmission system, it can only use Existing technology 3, resulting in low transmission efficiency of the system as a whole
