Non-uniform complexity measures originated in automata and formal languages theory are characterized in terms of well-known uniform complexity classes. The initial index of languages is introduced by means of several computational models. It is shown to be closely related to context-free cost, boolean circuits, straight line programs, and Turing machines with sparse oracles and time or space bo...

Few existing image defogging or dehazing methods consider dense and non-uniform particle distributions, which usually happen in smoke, dust fog. Dealing with these and/or distributions can be intractable, since fog’s attenuation airlight (or veiling effect) significantly weaken the background scene information input image. To address this problem, we introduce a structure-representation network...
