Order
Round the S of all pixels of width of cloth texture image again
BestMean value as the measurement of the roughness descriptor of this texture.
Step 4, calculated a width of cloth texture after, this texture image needn't be preserved, the storage capacity requirement to dsp is lower like this, but the result that will preserve in (6) estimates as the roughness of this width of cloth texture; Analyze the requirement whether the roughness intensity of variation reaches threshold value based on the threshold value that is provided with in advance (this part that is arranged on of threshold value illustrates afterwards); If reach then send signal; The control stove and accessory transfers slow fire or low power state to, and closes fiery after the time reaching preset slow fire; Otherwise change step (1), continue to take the photograph the congee that a width of cloth boiling, the texture image of milk at a distance from the δ second beats through camera is every.
Because the calculating of roughness is based on the not mean bias of overlaid windows, so be insensitive, just have the illumination unchangeability to the light and shade of environment and the direction of illumination of light, increased the stability of differentiation.
Experimental result shows that various congee, milk have similar Changing Pattern, and is as shown in Figure 2.
Horizontal ordinate is the image of taking at a distance from 1 second time according to every among Fig. 2, time shaft just, and ordinate is the roughness descriptor that calculates according to the method described above.Along with continuing to boil; Find the rule of conversion of the roughness of various congee; The value that is the roughness of every kind of congee all is to follow the rule of conversion of falling after rising; The image that photographs that the peak of the roughness curve of every kind of congee is corresponding is congee corresponding state when just having boiled just, and such image shows that this moment, various congee were in the state that has just boiled, and what after this take is the increasing texture image of the degree of boiling.Find that through experiment the curve of maize gruel of change curve and Fig. 2 that boils milk is very similar; And no matter boil other various milk products, its change curve and milk are all basic identical; Again because boil milk after detecting threshold value; Slowly stewed without slow fire; The slow section time of fire or slow fire of can closing immediately is set to zero, so suchly stew asynchronism(-nization) slowly because of slow fire 6 buttons need be set unlike cooking congee, the button that an expression boils milk only need be set get final product.Because the various congee in detected roughness peak place, milk all are in and have just begun the state that boils, send the slow fire control wave so threshold value is selected in to detect when maximal roughness has descended certain several roughness unit, the control stove and accessory is to the slow fire state.The threshold value of finding various congee through experiment is approximately 2; If promptly detect after historical high roughness C; The roughness decline degree of image reaches two units, can confirm that then historical high roughness C is the maximal value of roughness, the moment that the pairing moment promptly comes to life; Simultaneously send the slow fire control wave in descend moment of 2 units of roughness ratio maximum roughness, and the fluidized state basically identical judged of this moment and human eye.
So above-mentioned analysis roughness changes the requirement that whether reaches threshold value, be the moment of judging 2 units of roughness ratio maximum roughness decline after historical maximal roughness, and send the slow fire control wave constantly in this.In fact, can be regarded as a kind ofly not having slow fire and stewing cooking congee of time slowly with boiling milk, descend behind two units when detecting roughness, directly closing fire, the slow fire time of stewing slowly promptly can or be set be zero.
' * ' among Fig. 2 is promptly according to the various congee of the threshold decision of establishing, the boiling point of milk (because be in the moment of 2 units that descend than maximum roughness, roughly be equivalent to boil the back and just send the slow fire control signal 5 seconds, so be not the peak of roughness).Through experiment will comprise mixed congee respectively, the be cut boiling point separately and the real scene shooting image of congee, barley gruel, oatmeal porridge, milled congee, maize gruel and milk contrasts greatly, results of comparison shows the boiling point extraction value of various congee and the judgement basically identical of human eye.
