1) I think you mean DOF - it stands for Dense Optical Flow.

Rio Chan said:
q2: DL inference on 0.3MP , what is the meaning?

2) Please refer to all these examples, the image that is fed into the C7x/MMA is 0.3MP resolution after downscaling. Please read more here: software-dl.ti.com/.../group_apps_dl_demos_app_tidl_avp2.html

Hi K:

So, in this link:https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/07_03_00_07/exports/docs/vision_apps/docs/user_guide/group_apps_dl_demos_app_tidl_avp2.html

where is the 0.3M calculated?

how is the formula to output or input 0.3M?

the value fed into C7X/MMA is 3x768x384 = 0.88M, but I don't know why to come out the 0.3M.

May you explain in detail?

Rio,

The 3 in that equation corresponds to the 3 different camera inputs in that demo (front, left and right). It is in effect 0.3M for each camera/input.

Hi K:

May you rehearsal in detail how to calculate 3x768x384 = 0.88M into 0.3M for this?

By what kinds of formula to come out the 0.3M?

Customer is evaluating the TDA4 DL performance, so, we need to understand 100% correct and to explain this to them.

Thank you very much.
