SSD khiav ib tug convolutional network ntawm input duab ib zaug thiab xam ib tug feature daim ntawv qhia. SSD kuj tseem siv cov thawv thauj tog rau nkoj ntawm ntau qhov sib piv zoo ib yam li Ceev dua - RCNN thiab kawm lub off-set es tshaj kawm lub thawv. Txhawm rau tswj qhov ntsuas, SSD kwv yees bounding thawv tom qab ntau convolutional txheej.

Tsis tas li ntawd, RCNN yog dab tsi?

Faster RCNN yog ib qho khoom tshawb nrhiav architecture nthuav tawm los ntawm Ross Girshick, Shaoqing Ren, Kaiming He thiab Jian Sun hauv xyoo 2015, thiab yog ib qho ntawm cov khoom nto moo nrhiav kom pom cov qauv uas siv cov kev sib txuas ntawm cov neural xws li YOLO (Koj Saib Tsuas Yog Ib Leeg) thiab SSD (Single Shot Detector).

Ib yam li ntawd, vim li cas RCNN sai dua? Yog vim li cas Ceev R-CNN ”yog sai dua tshaj R-CNN yog vim tias koj tsis tas yuav pub 2000 cov lus pom zoo hauv cheeb tsam rau lub convolutional neural network txhua zaus. Hloov chaw, kev ua haujlwm convolution tsuas yog ua tiav ib zaug ib daim duab thiab ib daim ntawv qhia tshwj xeeb yog tsim los ntawm nws.

Yog li ntawd, vim li cas SSD sai dua Yolo?

Piv rau zawv zawg qhov rais thiab cheeb tsam cov tswv yim txoj kev lawv muaj ntau sai dua thiab yog li tsim nyog rau kev tshawb pom cov khoom hauv lub sijhawm. SSD (uas siv ntau daim ntawv qhia convolutional feature maps nyob rau sab saum toj ntawm lub network es tsis txhob tag nrho cov khaubncaws sab nraud povtseg raws li YOLO ua) yog sai dua thiab muaj tseeb dua tshaj YOLO.

Yolo ceev npaum li cas?

Qhov ceev tshaj plaws architecture ntawm YOLO muaj peev xwm ua tiav 45 FPS thiab ib qho me me version, Tiny- YOLO , ua tiav mus txog 244 FPS (Tiny YOLOv2) ntawm lub computer nrog GPU.
